Answer:
x = 9
Step-by-step explanation:
→Distribute the 5 to (x + 7), Distribute the -3 to (x - 4):
5(x + 7) - 3(x - 4) = 7x + 2
5x + 35 - 3x + 12 = 7x + 2
→Add like terms:
2x + 47 = 7x + 2
→Subtract 2x from both sides:
47 = 5x + 2
→Subtract 2 from both sides:
45 = 5x
→Divide both sides by 5:
9 = x
