Solving Systems of Linear Equations by Elimination
... Step 3: Add the new equations to eliminate a variable. The sum should be an equation with just one variable. Step 4: Solve the equation from Step 3 for the remaining variable. Step 5: Substitute the result from Step 4 into either of the original equations, and solve for the other variable. Step 6: C ...

... Therefore the correct solution is (3x - 2)(x + 3) Now if the equation had been given as 3x2 + 7x –6 = 0 then (3x - 2)(x + 3) = 0 Thus either (3x - 2) = 0 or (x + 3) = 0 This reasoning may be used to determine the roots of the equation (the algebraic values) ...
