5x - 7y = 5 (subtract both sides by 5x)
-7y = -5x + 5 (divide both sides by -7)
y = (5x - 5)/7
If you want to solve for y = 0, then x = 1.

5x = 15 so x = 15/5 = 3
15x+7y = 4 5x+7y = 2 Subtract the bottom equation from the top equation to eliminate y which will leave you with: 10x = 2 Divide both sides by 10 to find the value of x: x = 2/10 = 1/5 in its lowest terms. Substitute the value of x into the original equations to find the value of y: Therefore: x = 1/5 and y = 1/7
5x-3=37 (Original Equation) 5x=40(Add 3 to the right side) x=8(Divide 40 by 5)
7
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
