Given the equaiton system, we can use the method of solving two equations to find the answer:
x+y=80
5x+8y=430
Break it down into two equaitons:
x+y = 80
y = 80 - x ...(1)
5x + 8y = 430...(2)
We can then use the method of substitution to find the answers:
Put (1) into (2),
5x + 8(80-x) = 430
5x + 640 - 8x = 430
-3x = 430 - 640
-3x = -210
x = 210/3
x = 70...(3)
Now thay we find x, we can put it into the first eqaution to find y:
x+y = 80
70+y = 80
y = 10
Therefore, x= 70 and y = 10.
Hope it helps!
