Question

Examine the system of equations. Y = 5x 6, y = x 10 Use substitution to solve the system of equations. What is the value of y? –11 –1 1 11.

Answer 1

(1,11)

Explanation:

I'll assume the equations have a "+" sign:

y = 5x + 6,

y = x + 10

==========

y = 5x + 6

x + 10 = 5x + 6 [Second equation substituted for the y in the first]

4x = 4

x = 1

----

y = x + 10

y = 1 + 10

y = 11

================
