B 10 4 Then use the value of b to find the value of v by substituting back into one of. In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
To solve a system of equations by elimination we transform the system such that one variable cancels out.
Solve for xNow that we have the equation 12x 13 from our elimination step we can easily solve for x. Solve for xNow that we have the equation 12x 13 from our elimination step we can easily solve for x. Graphing will have you sketch both curves to visually find the points of intersection. Choose a variable to eliminate say x and select two equations with which to eliminate it say equations 1 and 2.
