24. x = -8.2
Step-by-step explanation:
1. x - 3.5 = 14.9 (add 3.5 to each side)
x = 18.4
2. x + 2.25 = 1 (subtract 2.25 from each side)
x = -1.25
3. -[tex]\frac{1}{3}[/tex] = x - [tex]\frac{3}{4}[/tex] (add [tex]\frac{3}{4}[/tex] to each side)
[tex]\frac{3}{4}[/tex] - [tex]\frac{1}{3}[/tex] = x (multiply [tex]\frac{3}{4}[/tex] by [tex]\frac{3}{3}[/tex] and [tex]\frac{1}{3}[/tex] by [tex]\frac{4}{4}[/tex] to get a common denominator)
[tex]\frac{9}{12}[/tex] - [tex]\frac{4}{12}[/tex] = x
[tex]\frac{5}{12}[/tex] = x
4. x - 2.8 = 9.5 (add 2.8 to each side)
x = 12.3
5. x - 8.5 = -2.1 (add 8.5 to each side)
x = 6.4
6. z - 9.4 = -3.6 (add 9.4 to each side)
z = 5.8
7. x + [tex]\frac{5}{6}[/tex] = [tex]\frac{11}{12}[/tex] (subtract [tex]\frac{5}{6}[/tex] from each side)
x = [tex]\frac{11}{12}[/tex] - [tex]\frac{5}{6}[/tex] (multiply [tex]\frac{5}{6}[/tex] by [tex]\frac{2}{2}[/tex] to get a common denominator)
x = [tex]\frac{11}{12}[/tex] - [tex]\frac{10}{12}[/tex]
x = [tex]\frac{1}{12}[/tex]
8. -[tex]\frac{5}{6}[/tex] + x = -[tex]\frac{13}{12}[/tex] (add [tex]\frac{5}{6}[/tex] to each side)
x = [tex]\frac{5}{6}[/tex] - [tex]\frac{13}{12}[/tex] (multiply [tex]\frac{5}{6}[/tex] by [tex]\frac{2}{2}[/tex] to get a common denominator)
x = [tex]\frac{10}{12}[/tex] - [tex]\frac{13}{12}[/tex]
x = -[tex]\frac{3}{12}[/tex] = -[tex]\frac{1}{4}[/tex]
9. x - [tex]\frac{1}{9}[/tex] = [tex]\frac{5}{18}[/tex] (add [tex]\frac{1}{9}[/tex] to each side)
x = [tex]\frac{1}{9}[/tex] + [tex]\frac{5}{18}[/tex] (multiply [tex]\frac{1}{9}[/tex] by [tex]\frac{2}{2}[/tex] to get a common denominator)
x = [tex]\frac{2}{18}[/tex] + [tex]\frac{5}{18}[/tex]
x = [tex]\frac{6}{18}[/tex] = [tex]\frac{3}{9}[/tex] = [tex]\frac{1}{3}[/tex]
10. x + 6 = -3 (subtract 6 from each side)
x = -9
11. z - 7 = 11 (add 7 to each side)
z = 18
12. -1 = x - 8 (add 8 to each side)
7 = x
13. -4x = 36 (divide each side by -4)
x = -9
14. -[tex]\frac{x}{3}[/tex] = 12 (multiply each side by -3)
x = -36
15. 63 = -9x (divide each side by -9)
-7 = x
16. 6.4 = 0.8x (divide each side by 0.8)
8 = x
17. -2.8z = 4.2 (divide each side by -2.8)
z = -1.5
18. -[tex]\frac{7}{9}[/tex]x = 5 (divide each side by -[tex]\frac{7}{9}[/tex])
x = [tex]\frac{5}{1}[/tex] ÷ -[tex]\frac{7}{9}[/tex]
x = [tex]\frac{5}{1}[/tex] (times) -[tex]\frac{9}{7}[/tex]
x = -[tex]\frac{45}{7}[/tex]
19. [tex]\frac{1}{2}[/tex]x = 8 (divide each side by [tex]\frac{1}{2}[/tex])
x = 16
20. -[tex]\frac{3}{4}[/tex]x = 9 (divide each side by -[tex]\frac{3}{4}[/tex])
x = -12
21. -[tex]\frac{7}{8}[/tex]x = -[tex]\frac{21}{64}[/tex] (divide each side by -[tex]\frac{7}{8}[/tex])
x = -[tex]\frac{7}{8}[/tex] ÷ -[tex]\frac{21}{64}[/tex]
x = -[tex]\frac{7}{8}[/tex] (times) -[tex]\frac{64}{21}[/tex]
x = [tex]\frac{448}{168}[/tex] = [tex]\frac{56}{21}[/tex] = [tex]\frac{8}{3}[/tex]
22. 1.6x = -3.2 (divide each side by 1.6)
x = -1.6
23. -[tex]\frac{1}{2}[/tex] = -[tex]\frac{5}{18}[/tex]x (divide each side by -[tex]\frac{5}{18}[/tex])
1.8 = x
24. -2.5x = 20.5 (divide each side by -2.5)
x = -8.2
