Question

Solve the following system of equations. What is the y-value of the solution? x + 5y - 10 = 0 x = 4y - 8

0
-2
2
4

Answer 1

y = 2

Explanation:

x + 5y - 10 = 0

x = 4y -8

We have the equation:

4y - 8 + 5y - 10 = 0

9y - 18 = 0

9y = 18

y = 2

Answer 2

x + y = 2

x+5y-10=x+4y-8
-4y -4y

x+y-10=-8
+10 +10

x+y = 2
