Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$8y+7=13$$

Answer

y=3/4

Solution


Subtract \(7\) from both sides.
\[8y=13-7\]
Simplify  \(13-7\)  to  \(6\).
\[8y=6\]
Divide both sides by \(8\).
\[y=\frac{6}{8}\]
Simplify  \(\frac{6}{8}\)  to  \(\frac{3}{4}\).
\[y=\frac{3}{4}\]

Decimal Form: 0.75
