Question

Is -6 a solution for the equation 3(2x - 8)= -4(-6 +21)?

Answer 1

YeS, it is a solution

Explanation:

Here, we want to check if -6 is a solution to the question

What we have to do is to replace x by -6

If what we have on the left equals that on the right, then -6 is a solution

Thus, we have it that;

3(2(-6) -8)

= 3(-12-8)

= 3(-20) = -60

for the right hand side

-4 (15) = -60

This means both sides are equal and that -6 is a solution
