WebAfter adding first equation twice into second one. 2⋅ (2x +7y)−4x+ y = 2⋅13−11 4x+14y− 4x +y = 26−11 15y = 15 ... -8x+7y=10 Geometric figure: Straight Line Slope = 2.286/2.000 = … WebSolution Step 1 Put the equation in standard form. We must subtract 6 from both sides. Step 2 Factor completely. Recall how to factor trinomials. Step 3 Set each factor equal to zero and solve for x. Since we have (x - 6) (x + 1) = 0, we know that x - 6 = 0 or x + 1 = 0, in which case x = 6 or x = - 1.
