The correct matches are shown in the picture after simplification of every expression.
What is an expression?
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.
