Answer:
Step-by-step explanation:
Solve the system:
8x−4y=20
4x−8y=4
Reduce the first equation by dividing every term by -2:
-4x + 2y = -10
and then combine this result with the second equation:
4x−8y=4
-4x + 2y = -10
--------------------
-6y = -6, and so y = 1.
According to the first equation, if y = 1, then 4x - 8 = 4, or x = 3.
Then x = 3 and y = 1.
So, finally, x - y = 3 - 1 = 2
108 = .36x
divide both sides by .36
300 = x
Answer:
Slope-intercept form is y=mx+b (m = gradient, b = y-intercept)
So we want to make y the subject.
3x + 4y =-24
4y = -3x - 24
y = (-3/4)x - 6
