Which of the following equations has the same solution

Question

8(x+2)=12

A. 8x+2=12

B. x+2=4

C. 8x=10

D. 2x+4=3

Answer 1

Hi Sydney H.

For

8(x + 2) = 12

Apply PEMDAS

Divide both sides of the equation by 4

You should get

Choice D, 2x + 4 =3

PEMDAS also rules out choices A, B, and C

Answer 2

Equation given in the math problem:

8(x + 2) = 12

8x +16 = 12

-16 -16

8x = -4

x = -1/2

Answer A:

8x + 2 = 12

-2 -2

8x = 10

x = 5/4

Answer B:

x + 2 = 4

-2 -2

x = 2

Answer C:

8x = 10

x = 10/8

x = 5/4

Answer D:

2x + 4 = 3

-4 -4

2x = -1

x = -1/2

Answer letter D has the same solution as the equation that was given in the problem above. They both have a solution of -1/2.
