Let's use substitution.
y=−2x+3
y=13x−4
1. Substitute
−2x+3=13x−4
2. Solve for x
x = 7/15
3. Substitute x into the equation
y = 31/15
The answer is
7/15, 31/15

since both the expressions in x are equal to y then they are equal to each other, so
-2x + 3 = 13x - 4
-15x + 3 = -4
-15x = -7
x = 7/15
and y = -2(7/15) + 3 = 31/15 = 2 1/15
