x-y = 6
-x-3y = 22
-4y = 28
y = -7
So by substituting: x = -1 and y = -7

4x+3y = 6 3y = -4x+6 y = -4/3x+2 in slope intercept form
x + 3y = 2 2x - 3y = 22 Add the two equations: 3x = 24 Divide both sides by 3 to give x= 8. Substitue this value of x in the first equation to give 8 + 3y = 2 Subtract 8 from both sides: 3y = -6 Divide both sides by 3: y = -2 Solution: (X, y) = (8, -2)
x = 3y - 3 so 6 (3y - 3) + 2y = -12 ie 18y - 18 + 2y = -12 ie 20y = 6 so y = 0.3 and x = -2.1

x = 5 y = 2 4x - 3y = ? 4(5) - 3(2) = ? 20 - 6 = 14
