Question

solve for x
$3(x + 1) = 5(x - 2) + 7$

Answer 1

3(x + 1) = 5(x - 2) + 7

• Distribute 3 and 5 inside their respective parentheses.

3x + 3 = 5x - 10 + 7

• Combine like terms.

3x + 3 = 5x - 3

• Add 3 to both sides.

3x + 6 = 5x

• Subtract 3x from both sides.

6 = 2x

• Divide both sides by 2.

x = 3

Answer 2

$3(x+1)=5(x-2)+7\\\\ 3x+3=5x-10+7\\\\ 2x=6\\\\ x=3$
