Question

-3(2x+7)=-51 what does x=

Answer 1

x=5

Explanation:

-3(2x+7)=-51

opening bracket in the left hand side

-3.2x+(-3).7=-51

-6x-21=-51

adding 21 on both sides

-6x=-51+21

-6x=-30

dividing both sides by -6

[tex]\frac{-6x}{-6}=\frac{-30}{-6}

x=5

Hence the value of x came out to be 5
