Answer 2

y=11

Explanation:

Solve the system by substitution by setting the equations equal to each other.

y = 5x+6

y = x+10

It becomes 5x+6 = x+10. Solve for x using inverse operations.

5x+6 = x+10

4x+6 = 10

4x = 4

x=1

Substitute x=1 into one equation to find y.

y = x+10

y = 1 +10

y=11
