You need two independent linear equations to solve for two variables, x and y. The most you can do with just one equation is to simplify:

y + 5x = 9

and then write one variable in terms of the other, if that is of any use.

y = 9 - 5x

x = (9 - y)/5

-8 + 10x = 18 10x = 18+8 10x = 26 x = 26/10 x = 2.6

Y equals 10x - 9 y equals x plus 18?

(3,21)

10x-18 equals 5x plus 2?

10x - 18 = 5x + 2 Add -5x + 18 to both sides of the equation, to get: 5x = 20, from which x = 4.
