Question

iven: x – (5 – 3x + 2) = 15 + 3x

Prove: x = 22

Mathematical Statement
Justification
x – (5 – 3x + 2) = 15 + 3x
Given
x – (5 + 2– 3x) = 15 + 3x

x – (7– 3x) = 15 + 3x

x – 7 + 3x = 15 + 3x

x + 3x – 7 = 15 + 3x
Commutative Property of Addition
4x – 7 = 15 + 3x
Combine Like Terms
x – 7 = 15
Subtraction Property of Equality
x = 22
Addition Property of Equality
