Step-by-step explanation:
Given
7x + 3x − 18 = 6(x + 3)
Distribute using the Distributive Property
7x + 3x − 18 = 6x +18
Combine like terms
10x -18 = 6x+18
Subtract 6x from each side Subtraction Property of Equality
10x -6x -18 = 6x +18-6x
Simplify
4x -18 = 18
Add 18 to each side Addition Property of Equality
4x -18+18 = 18+18
Simplify
4x = 36
Divide each side by 4 Division Property of Equality
4x/4 = 36/4
