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

x=9
Step-by-step explanation:
5 (x + 7) - 3 (x - 4) = 7x + 2
Distribute
5x+35 - 3x + 12 = 7x + 2
2x + 47 = 7x+2
Subtract 2x from each side
2x+47-2x = 7x - 2x+2
47 = 5x+2
Subtract 2 from each side
47-2 = 5x+2-2
45 = 5x
Divide by 5
45/5 = 5x/5
9 = x
