In order to solve that equation, you need to get your X's on one side and your numbers on the other. First, you subtract 2X from both sides to get -10= -2 +16X. Then, you add 2 to both sides to get -8=16X. Finally, you divide both sides by 16 to get the X by itself to get X=-.5.

2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)

Using the quadratic equation formula: x = 1 or x = -10
x = -8
