The correct matches are shown in the picture after simplification of every expression.
<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.
