Example

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

Question

$$7x-2=4x+5$$

Answer

x=7/3

Solution


Add \(2\) to both sides.
\[7x=4x+5+2\]
Simplify  \(4x+5+2\)  to  \(4x+7\).
\[7x=4x+7\]
Subtract \(4x\) from both sides.
\[7x-4x=7\]
Simplify  \(7x-4x\)  to  \(3x\).
\[3x=7\]
Divide both sides by \(3\).
\[x=\frac{7}{3}\]
