Answer:
x = 3 y = -1
Step-by-step explanation:
x - 5y = 8
x = 5y + 8
replace x with 5y + 8 in the other equation
4(5y + 8) + 5y = 7
20y + 32 + 5y = 7
25y = 7 - 32
25y = -25
y = -25/25
y = -1
x = 5(-1) + 8
x = -5 + 8
x = 3
Answer:
b) x = 24
Step-by-step explanation:
if y is 24 and x is 16, they make the fraction 
this can be simplified to 
if you divide both sides of the fraction by 8.
36/3 is 12, and 12 * 2 = 24.
so, x = 24
