Sagot :
Answer:
no
Step-by-step 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
