WebTo solve a system of equations by elimination, write the system of equations in standard form: ax + by = c, and multiply one or both of the equations by a constant so that the coefficients of one of the variables are opposite. Then, add or subtract the two equations to eliminate one of the variables. Solve the resulting equation for the ... WebGraph. Quiz. Simultaneous Equation. 5 problems similar to: 2x-y = 4x+2y = 8. ... -2x-3y=0,4x+2y=8 . In order to solve by elimination, coefficients of one of the variables must … WebSo we have 5x plus 2y is equal to 20. If we want to solve for y, let's just get rid of the 5x on the left-hand side. So let's subtract 5x from both sides of this equation. The left-hand side, these guys cancel out, so we get 2y is equal to the right hand side, you have 20 minus 5x. And then you can divide both sides of this equation by 2. how to doctor up canned yams
