Question

-

Is -2 a solution to the equation 2x – 8= 3(x - 1) - 2x ?
yes, -2 is the correct solution
А
B no, -2 is not the correct solution
there is not enough information to determine this

Answer 1

no

Explanation:

Substitute x = - 2 into the equation and if both sides are equal then it is a solution to the equation.

left side = 2(- 2) - 8 = - 4 - 8 = - 12

right side = 3(- 2 - 1) - 2(- 2) = 3(- 3) + 4 = - 9 + 4 = - 5

left side ≠ right side

Then x = - 2 is not a solution to the equation
