Solve for one variable x or y first. So lets solve for x. If you take the first equation x= -12 -5y. You then plug that into the second equation
5(-12-5y) +4y = 24
now you solve for y
-60 - 25y + 4y =24
-21y=84
y=-4
Now you plug in y back into either equation and you get x=8
A may be not sure but good luck
Answer:
y = 4
Step-by-step explanation:
KM / 10 = KO / 16
(4y - 1) / 10 = 6y / 16
KO = 4y-1 + 2y+1 = 6y
cross-multiply:
60y = 64y - 16
-4y = -16
y = 4
If the two triangles are congruent it means that their side lengths are equal, so we can assume that x = 3x - 8 and so 2x = 8 and x = 4. Hope that helps :)
