Answer:
B. 3
Step-by-step explanation:
→You need to get rid of the (-x + 4) in the denominator, and to do so, you must multiply both sides by it:
[tex]\frac{2x-3}{-x+4} =3[/tex]
2x - 3 = 3(-x + 4)
→Distribute the 3 to (-x + 4):
2x - 3 = -3x + 12
→Add 3x to both sides:
5x - 3 = 12
→Add 3 to both sides:
5x = 15
→Divide both sides by 5:
x = 3
