Answer:
Step-by-step explanation:
Not much you can do with this single equation in two variables other than to solve it first for one variable and then for the other:
7y+23
If 8x - 7y = 23, then 8x = 7y + 23, or x = ------------
8
and:
23 - 8x
If 8x - 7y = 23, then -7y = 23 - 8x, or y = --------------
-7
