Answer:
Step-by-step explanation:
To find a solution of this equation, that is easy.
You can take a value of x ( or y), then replace this value to find the value of the reste variable.
For example, you can take x =0 ( that is so easy)
Replace x= 0 into 5x - 2y =18
you find: 5*0 -2y = 18
or -2y =18
and y = 18/-2
y = -9
So, you find a solution (0, -9).
