Question

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

Answer 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

Answer 2

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
