Answer:
The answer is (-5,2)
Step-by-step explanation:
So we have 2 equations and we need to solve them by substitution.
1) y = 4x + 22
2) 4x – 6y = –32
Since we already have y isolated in equation #1, we'll use that value in equation #2:
4x - 6(4x + 22) = -32
4x - 24x - 132 = -32
-20x = 100
x = -5
Then we put that value of x in the first equation:
y = 4 (-5) + 22 = -20 + 22 = 2
The answer is then (-5,2)
Answer:
(-5, 2)
Step-by-step explanation:
We have the equations:
[tex]y=4x+22[/tex] and [tex]4x-6y=-32[/tex]
Using the substitution method, with y = 4x + 22 and replace it in the equation 4x - 6y = -32
4x - 6(4x + 22) = -32
4x -24x -132 = -32
-20x = -32 + 132
x = 100/-20= -5
Substituting the value of x in the first equations of the systems to clear x.
y = 4x + 22
y = 4(-5) + 22
y= -20 + 22 = 2
