Answer:
(- 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 )
Answer:
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.
