Answer:
x= 7
y= -2.75
Step-by-step explanation:
It's a system of equations so you have to use elmination to get a varibale.
I elminiated the y by multipling 5x+4y=24 by 2 and combining the two equations.
So now we are on 12x= 84. solve
x=7
plug it back into any formula, I chose 2x-8y=36 and solve for y
and you get the answer, Voila!
Answer:
5x + 4y = 24 (-4/5y + 24/5)
2x - 8y = 36 (4y + 18)
Step-by-step explanation:
Add -4y to both sides 1) 5x + 4y (-4y) = 24 (-4b)
Divide both sides by 5 2) 5x/5 = -4y+24/5
3) x = -4/5y + 24/5
Add 8y to both sides 1) 2x - 8y (8y) = 36 (8y)
Divide both sides by 2 2) 2x/2 = (8y + 36)/2
3) 4y +18
