x = - 5, y = 3 or you can write it as (-5, 3).
Step-by-step explanation:
y=-8x - 37
x+3y=4
From the second equation x = 4 - 3y, so substituting in equation 1:
y = - 8 (4 - 3y) - 37
y = - 32 + 24y - 37
-23y = - 69
y = 3
Now plug y = 3 into equation 1:
3 = - 8x - 37
-8x = 40
x = - 5.

( - 5, 3)
Step-by-step explanation:
Given the 2 equations
y = - 8x - 37 → (1)
x + 3y = 4 → (2)
Substitute y = - 8x - 37 into (2)
x + 3 ( - 8x - 37) = 4 ← distribute and simplify left side
x - 24x - 111 = 4
- 23x - 111 = 4 (add 111 to both sides)
- 23x = 115 (divide both sides by - 23)
x = - 5
Substitute x = - 5 into (1) for corresponding value of y
y = - 8 ( - 5) - 37 = 40 - 37 = 3
Solution is ( - 5, 3)
