Example

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

Question

$$2x-5=3x+4$$

Answer

x=-9

Solution


Subtract \(2x\) from both sides.
\[-5=3x+4-2x\]
Simplify  \(3x+4-2x\)  to  \(x+4\).
\[-5=x+4\]
Subtract \(4\) from both sides.
\[-5-4=x\]
Simplify  \(-5-4\)  to  \(-9\).
\[-9=x\]
Switch sides.
\[x=-9\]
