Look at the image down below: Also here the answer choices:
A- x = 2
B- x = 0.5
C- x = -2
D- x = -0.5

A: x = 2

Step-by-step explanation:

Knowing that the answer is supposed to be 10 = 10, we need to make both sides equal in order for it to be true.

The equation displays 3x + 4 = 10.

If x were to equal 2, 3 times 2 would be 6.

6 + 4 is 10, which makes our equation, 10 = 10.

Hope this helped! :)
