9y-3y=6y; 6y+2y=8y; so your answer is 8y

9y = 12.6 y = 1.4

The slope is 0.

(1, -1)

9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5

its 10x +9y +1z

57+9y=81y+12 45=72y 45/72=y

x = 2, y = 1

13x - 9y - 10

(y + 6)(y + 3)

-3x+9y = 6 9y = 3x+6 y = 1/3x+2/3

10y = 9y + 4, so y = 4

y = 4/5 or 0.8

9y - 4x

9y+3=5y+13 4y=10 y=10/4 or 5/2 or 2.5

12y+3=9y-15 3y=-18 y=-6

x=9 y=1

(0,7)

I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43

9y subtract 11 equals 7

well we can't simiply solve that problem. we must no what y= to solve this. So u can only simpify ok combine like terms. 2y plus 9y is 11y. your answer is 11y+9

-7x+9y = 54 9y = 7x+54 y = 7/9x+6 which is now in slope-intercept form

9 + 9y = 27x -9 -9 9y = 27x - 9 9y/9 = 27x/9 - 9/9 y = 3x -1

-4x + 9y = 0 is the equation of a line in the Cartesian plane and the coordinates of any of the infinite number of points on that line will satisfy the equation.

-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
