If x equals 10 and y equals 10, then 9x plus 8y equals 170.

To solve for two unknown variables (x and y) you require two independent equations,

9x+27 = -81 9x = -81-27 9x = -108 x = -12

x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0

10x=x 9x=0 x=0

2x+3=9x =>3=7x =>3/7=x

2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x

2x+3 = 9x 3 = 9x-2x = 7x 7x = 3 x = 3/7

9x + y = 22to solve for x-subtracy y from both sides --> 9x = 22 - ydivide by 9 on both sides --> x = (22/9) - (y/9)to solve for y - subtract 9x from both sides --> y = 22 - 9x

-2x2 + 9x - 12 = 0Then apply the quadratic formula.

x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3

it equals 13X.

x + 8x = 477 9x = 477 x = 53

2x + 9x simplified would be 11x

The slope is 0.

2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x
