Example

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

Question

$$4-x/6=7$$

Answer

x=-18

Solution


Subtract \(4\) from both sides.
\[-\frac{x}{6}=7-4\]
Simplify  \(7-4\)  to  \(3\).
\[-\frac{x}{6}=3\]
Multiply both sides by \(6\).
\[-x=3\times 6\]
Simplify  \(3\times 6\)  to  \(18\).
\[-x=18\]
Multiply both sides by \(-1\).
\[x=-18\]
