WebSo one way to solve these systems of equations is to graph both lines, both equations, and then look at their intersection. And that will be the solution to both of these equations. In … WebThe left-hand side, we're left with just a 2y, and then the right-hand side becomes 6x minus 4. So 2y is equal to 6x minus 4. And then to get everything in terms to solve for y, we just have to divide everything by 2. So let's divide everything by 2, and we get y is equal to 3x minus 2.
