Question

What is the solution to the equation 2x + 4 = 24? x = 1 x = 3 x = 6 x = 10

Answer 1

Answer:

d is the correct answer

Step-by-step 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

Answer 2

Answer:

    x = 14

Step-by-step 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
