Answer:

no solution

Explanation:−4(5 − 3x) = 12x + 20

−20 + 12x = 12x + 20

−20 = 20 → Since the values are not equal, there is no solution.

−4(5 − 3x) = 12x + 20

Solve for x:

First use the Distributive property:

-20 + 12x = 12x +20

Add 20 to both sides:

12x =12x + 40

Now you can't get X by itself, because both sides of the equation have the same quantity of x ( they both have 12x).

This means there is no solution.
