Answer:

x = 2

Given:

y = -3x + 11

y = 2x + 1

Step-by-step explanation:

[tex] = > - 3x + 11 = 2x + 1 \\ \\ = > - 3x - 2x = 1 - 11 \\ \\ = > \cancel{- }5x = \cancel{ - }10 \\ \\ = > 5x = 10 \\ \\ = > x = \frac{10}{5} \\ \\ = > x = 2[/tex]

To solve for y in this, you just substitute one equation for the value of y.

-3x+11=2x+1
5x=10
x=2

Then to get the x you substitute 2 into x in either equation.

2=2x+1
1=2x
1/2=x
