Step 1: Eliminate x from both the equations by making the coefficient of x in one equation opposite to the other. Step 2: [Multiply Equation 1 by 5.] 20x + 5y = 90 Step 3: [Multiply Equation 2 by 4.]- 20x - 8y = -84 _______________ Step 4: [Add the equations.] -3y = 6 Step 5: [Solve for y .] y = - 2 Step 6: [Substitute y = - 2 in Equation 1.]4x + (- 2) = 18 Step 7: [Solve for x .]x = 5 Step 8: The solution for the linear system is (5, - 2).
