what is 16x+9=9y-2x

16x + 9 = 9y - 2x

-16x - 16x

9 = 9y - 18x

-9y - 9y

-9y + 9 = - 18x

- 9 - 9

- 9y = - 18x - 9 (divide each side by - 9)

y = 2x + 1

Solve for x.

16x+9=9y-2x

Add 2x to both sides.

16x+9+2x=-2x+9y+2x

18x+9=9y

Add - 9 to both sides.

18x+9+-9=9y+-9

18x=9y-9

Divide both sides by 18.

18x/18 = 9y-9/18

x = 1/2y + - 1/2

solve for y.

16x+9=9y-2x

Flip the equation.

-2x+9y=16x+9

Add 2x to both sides.

-2x+9y+2x=16x+9+2x

9y=18x+9

Divide both sides by 9.

9y/9=18x+9/9

y=2x+1
