Answer:
First, you have to see if there is y= or x = to substitute for the equation to find the solution.
y = 2x + 1
Rewrite the equation in slope-intercept form.
2x - y = 3 -> y = 2x + 3
Add both equations together. Substitute.
2x+1 2(1)+1 = y
+ 2x+3 2 + 1 = y
y = 3
y= 4x + 4
4x =4
x = 1
Your answer should be (1,3).
