Question

3x divided by -8 = -21 divided by 4. The answer is 14. I'm trying =g to figure out why it was not a negative 14

Answer 1

See explanation

Explanation:

3x/(-8)=-21/4

-3x/8=-21*8/4

-3x*8/8=-21*8/4 ==> multiply 8 on both sides to get rid of denominator

-3x=-21*2

-3x=-42

3x=42 ==> Multiply by -1 on both sides to get positive values on both sides

x=14
