This one is simple since we already have the two x variables.equal. All we have to do is subtract the equations from one another to get the answer.
So i will subtract the left side by the other left side and the right side by the other right side
-8x - 8y -(-8x + 2y) = 0 -(-20)
distribute negative sign
-8x - 8y + 8x - 2y = 0 + 20
do the math
- 10y = 20
Y = -2
plug t into an equation
-8x -8 (-2) = 0
-8x + 16 = 0
-8x = -16
x = 2
answer (2, -2)

Your method is right so u already know how to do it
Answer:
q = 16
Step-by-step explanation:
3(q - 7) = 27
3q - 21 = 27
3q = 27 + 21
3q = 48
q = 48/3
q = 16
