<h3>What is an expression?</h3>It is defined as the combination of constants and variables with mathematical operators.
We have expressions shown in the picture:
First expression:
= 12x + 8 - 7x - 10
= 5x -2
Second expression:
= 17x/3 + 17 - 2x/3 - 15
= 5x + 2
Third expression:
= 8 - 12x - 10 + 7x
= - 5x - 2
Fourth expression:
= 9 - 9x/2 -x/2 - 7
= -5x + 2
Thus, the correct matches are shown in the picture after simplification of every expression.

If you <em>deposit</em> $35, you can imagine drawing a green line (representing the money gained) to the 35 on the number line, which can be seen as <em>moving </em>35 to the right<em />. Fo <em>w</em><em>ithdrawing, </em>imagine drawing a red line back 50 notches on the number line (representing money lost). The net effect that the deposit and withdrawal will have on your account balance is a 
dollar <em>loss</em>, which can be represented on the number line as a line drawn to the point -15.
