Example

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

Question

$$\left. \begin{array} { l } { 124 - ( 12 - 2 ) \times 9 } \\ { ( 18 + 2 ) - } \end{array} \right.$$

Answer

124*Si*IM*m*p*l*f*y-10*9;*20-65

Solution


Simplify  \(12-2\)  to  \(10\).
\[\begin{aligned}&Simpl\imath fy\times 124-10\times 9\\&(18+2)-65\end{aligned}\]
Simplify  \(18+2\)  to  \(20\).
\[\begin{aligned}&Simpl\imath fy\times 124-10\times 9\\&\times 20-65\end{aligned}\]
Regroup terms.
\[\begin{aligned}&124Si\imath mplfy-10\times 9\\&\times 20-65\end{aligned}\]
