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

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
