Answer 1

We have the following:

Solve for y in one move

1.

`\begin{gathered} 2y=5x+10 \\ y=(5)/(2)x+5 \end{gathered}`

2.

`\begin{gathered} 12+y=4x \\ y=4x-12 \end{gathered}`

3.

`\begin{gathered} 40x=y-12 \\ y=40x+12 \end{gathered}`

4.

`\begin{gathered} -y=9x-14 \\ y=-9x+14 \end{gathered}`

5.

6.

`\begin{gathered} 9y=3x+18 \\ y=(3x+18)/(9)=(1)/(3)x+2 \end{gathered}`

Solve for y from Standard Form in two or more move

7.

`\begin{gathered} 7x+3y=3 \\ 3y=3-7x \\ y=(3-7x)/(3) \\ y=1-(7)/(3)x \end{gathered}`

8.

`\begin{gathered} x+8y=-16 \\ 8y=-16-x \\ y=(-16)/(8)-(x)/(8) \\ y=-2-(x)/(8) \end{gathered}`

9.

`\begin{gathered} 12x+7y=28 \\ 7y=28-12x \\ y=(28)/(7)-(12)/(7)x \\ y=4-(12)/(7)x \end{gathered}`

10.

`\begin{gathered} 4x-2y=16 \\ 2y=-16+4x \\ y=-(16)/(2)+(4x)/(2) \\ y=-8+2x \end{gathered}`

11.

`\begin{gathered} 5x-3y=15 \\ 3y=5x-15 \\ y=(5)/(3)x-(15)/(3) \\ y=(5)/(3)x-5 \end{gathered}`

12.

`\begin{gathered} 2x+11y=33 \\ 11y=33-2x \\ y=(33)/(11)-(2)/(11)x \\ y=3-(2)/(11)x \end{gathered}`
