5 (x² -x -20)
We need two numbers that add to -1 and multiply to -20. -5 and 4 satisfy this.

Answer:
x=1 and y= -4
Step-by-step explanation:
step one: plug -4x into y in thi]e first equation.
2x+5(-4)= -18
step two: solve for x
2x-20= -18
(add 20 to both sides to eliminate -20 on the right)
2x=2
(divide both sides by 2 to get x by its self)
x=1
step 3: now that we found the value for x plug it in to either equation and solve for y
y= -4x
y= -4(1)
y= -4
Answer:
9x + 5y + -84 . (3x) + y = -18
