Solution
1) Simplify
<span> to </span>
<span>−2= </span>
+ 
2) Simplify + <span>to <span>914</span>
</span> <span>−2= </span>
3) <span>Add 2 to both sides
</span> = <span>+2
</span>
4) Simplify
<span><span>+2</span> to </span>
=
5) <span>Multiply both sides by 7
</span><span>4y= </span> <span>×7
</span>
6) Simplify <span><span>×7</span> to </span>
=
7) Simplify<span> to </span>
=
8) <span>Divide both sides by 4
</span>y= <span>×4
