Distribute (multiply): 5x + 10 = 3x + 5; subtract 5 from both sides
5x + 5 = 3x; subtract 5x from both sides
5 = -2x; divide both sides by -2
-2.5 = x
Substitute to make sure it's right. 5(-2.5 + 2) = 3(-2.5) + 5
5(-0.5) = -7.5 + 5
-2.5 = -2.5
Answer:
x = -2.5
Step-by-step explanation:
5(x+2) = 3x +5
Distribute the 5 on the left side
5x + 10 = 3x + 5
Subtract 3x from both sides
2x + 10 = 5
Subtract 10 from both sides
2x = -5
Divide by 2, in order to isolate x
x = -2.5
