How do you solve 3y=11-2x and 3x=y-11?
Doing some linear algebra, you find that x=-2 and y=5
Set up both equations so y (and coefficients) is alone on the left-hand side (LHS). The first one is already done for you:
Multiply the second equation by 3, and then subtract equation 2 from equation 1:
Solving for x:
Now, pick either starting equation and plug in x to solve for y:
