Answer:
x = 0 , y = 1
Step-by-step explanation:
x - 5y = -5
+5y +5y
-------------------
x = -5 + 5y
4x + 20y = 20
4(-5 + 5y) + 20y = 20
-20 + 20y + 20y = 20
-20 + 40y = 20
+20 +20
---------------------------------
40y = 40
/40 /40
----------------------------------
y = 1
x = -5 + 5y
x = -5 + 5(1)
x = -5 + 5
x = 0
So, using the method of substitution, we get x = 0 and y = 1.
Answer:
I agree with manamoto13 , the answer is y= 1 and x=0
