Please help timed !!!

Answer 1

x=10 Hope this helps!

Answer 2

Step-by-step explanation:Step 1 :

Equation at the end of step 1 :

2 • (x - 4) - 12 = 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

2x - 20 = 2 • (x - 10)

Equation at the end of step 3 :

2 • (x - 10) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2 Solve : x-10 = 0

Add 10 to both sides of the equation :

x = 10

One solution was found :

x = 10
