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

6x+11=92-3x +3x +3x 9x+11=92 -11 -11 9x=81 divide by 9 x=9

Type your answer here... 81

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

-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5

(9x)2 +9x/(45x)2 +81= 9+9x/86

its 81

That is an equation.Oh, you wanted to know for which values of x that equation is true? Okay...6x + 3x + 8 = 35⇔ (6x + 3x) + 8 = 35⇔ 9x + 8 = 35⇔ 9x + 8 - 8 = 35 - 8⇔ 9x + 0 = 27⇔ 9x = 27⇔ 9x / 9 = 27 / 9⇔ x = 27 / 9⇔ x = 3

it equals 13X.

The slope is 0.

12x + 6=9x + 27 12x-9x + 6=9x - 9x + 27 subtract 9x from both sides. 3x + 6 = 27 simplify 3x + 6 - 6=27 - 6 subtract 6 from both sides. 3x=21 simplify 3x/3=21/3 divide both sides by 3 x=7 simplify 12(7) + 6=>84+6=>90 9(7) + 27=>63+27=>90 It checks out!

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

6x+11=92-3x +3x +3x 9x+11=92 -11 -11 9x=81 divide by 9 x=9
