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)

Answer:
237 ⁹/23% change
Step-by-step explanation:
115=100%
337-155=273 which represents the increase
115=100
273=?
273×100÷115= 237 ⁹/23%
Answer =237⁹/23%
