The RHS = y for both, so set them equal to each other and find x.
Then find y.

Find the point of intersection on a pair of straight lines.
Y=3x-15
Y=-2x+10
The point of intersection is expressed in terms of x and y.
Solve first for x by eliminating y. Deduct first equation by the second equation.
(y-y) = (3x- -2x) -15-10
0 = 5x -25
5x = 25
x = 5
Substitute x = 5 in first equation
y = 3(5) -15
y = 0
The point of intersection is (5,0).
