\[-2(7-y)\times 4=-4\]

1
Simplify  2(7y)×4-2(7-y)\times 4  to  8(7y)-8(7-y).
8(7y)=4-8(7-y)=-4

2
Divide both sides by 8-8.
7y=487-y=\frac{-4}{-8}

3
Two negatives make a positive.
7y=487-y=\frac{4}{8}

4
Simplify  48\frac{4}{8}  to  12\frac{1}{2}.
7y=127-y=\frac{1}{2}

5
Subtract 77 from both sides.
y=127-y=\frac{1}{2}-7

6
Simplify  127\frac{1}{2}-7  to  132-\frac{13}{2}.
y=132-y=-\frac{13}{2}

7
Multiply both sides by 1-1.
y=132y=\frac{13}{2}

Done

Decimal Form: 6.5
