Given equations are y = 7x − 8 and y = 5x − 2

We can solve them easily using substion.

Plug y = 7x − 8 into y = 5x − 2

7x − 8 = 5x − 2

or 7x − 5x =8 − 2

or 2x = 6

or 2x/2 = 6/2

or x=3

Now plug x=3 into any of given equations say y = 5x − 2

y = 5(3) − 2=15-2=13

Hence (3,13) is the final answer.
