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+23If 8x - 7y = 23, then 8x = 7y + 23, or x = ------------ 8and: 23 - 8xIf 8x - 7y = 23, then -7y = 23 - 8x, or y = -------------- -7
