Answer:
X = 5
Step-by-step explanation:
First expand, 7x + 15 - 9x = 5
Simplify, -2x + 15 = 5
Additive property of Addition/Subtraction , (-2x + 15) - 15 = (5) -15
Simplify, -2x = -10
Divide by -2, (-2x)/-2 = (-10)/-2
Simplify, x = 5
Substitution for checking your answer, 7(5) + 3(5-3(5)) = 5
35 + (15-45), simplify, 35 - 30 = 5
Thus the final answer can be concluded as X = 5
