Is -2 a solution to 8=3x + 4

No.

Step-by-step explanation:

8 = 3 (-2) + 4

3 (-2) = -6

-6 + 4 = -2

Answer is -2 which does not equal 8, so no.

No

Step-by-step explanation:

Substitute -2 in for x to solve:

8 = 3(-2) + 4

8 = -6 + 4

8 ≠ -2

Because both sides of the equation do not equal the same thing, -2 is not a solution for the given equation.
