Answer:

C

Step-by-step explanation:

Put x as 4.

4 + 8 = 3(4)

12 = 12

True.

The equation that has the solution x = 4 is x + 8 = 3x.

Given that,

  • The x = 4.

Based on the given options,

(a) 4x = 20

Now if we put x value in the equation

Put x as 4

So

4x = 20

4(4) = 20

8 = 20

(b)

x ÷ 2 = 8

4 ÷ 2 = 8

2 = 8

(c)

x + 8 = 3x

(4) + 8 = 3(4)

12 = 12

Therefore we can conclude that the equation that has the solution x = 4 is x + 8 = 3x.
