Answer:

yes

Step-by-step explanation:

Substitute x = - 8 and y = - 7 into the equation

If both sides are equal then (- 8, - 7) is a solution

left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14

right side = 2y = 2(- 7) = - 14

Since both sides are equal then (- 8, - 7) is a solution to the equation
