Question

Solving Multi-Step Equations
12 - 10x + 5x = -18

Answer 1

x=6

Explanation:

10*x-5*x-3*x-(12)=0

1.1 Pull out like factors :

2x - 12 = 2 • (x - 6)

2.1 Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

2.2 Solve : x-6 = 0

Add 6 to both sides of the equation :

x = 6

Answer 2

x = 16
