Question

What is the solution to the equation 2x + 4 = 24?

x = 1
x = 3
x = 6
x = 10

Answer 1

x = 14

Explanation:

1.1 Pull out like factors :

2x - 20 = 2 • (x - 10)

Equation at the end of step 1 :

Step 2 :

Equations which are never true :

2.1 Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : x-10 = 0

Add 10 to both sides of the equation :

x = 10

One solution was found :

x = 10

Answer 2

d is the correct answer

Explanation:

1. 2(1)+4=2+4=8
2. 2(3)+4=6+4=10
3. 2(6)+4=12+4=16
4. 2(10)+4=20+4=24
