Answer:
Step-by-step explanation:
You have two variables and only one equation so you cannot solve for the variables numerically. (To solve for n variables you need n equations.) The most you can do is to solve for either variable in terms of the other variable. Whatever variable you care to solve for must be isolated by itself on one side of the equation. Suppose we wish to solve for y in terms of x.
-7x+3y=2 we add 7x to each side
3y=7x+2 we then dive each side by 3
y=(7x+2)/3
Similarly we can solve for x in terms of y
-7x+3y=2 subtract 3y from each side
-7x=2-3y divide each side by -7
x=(3y-2)/7
