Explanation:
Given statements:
1. Find the sum of -7g and 4g + 2
2. Find the difference when 6h is subtracted from 2h - 4
a) To write an expression based on the given statement
b) To simplify the expression
Solution:
1) The sum of -7g and 4g + 2 is given as:
1 a)
![-7g+4g+2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/py3vir3r7tcuo0edzvu68k68kqaxxqndq3.png)
This can be simplified by combining the like terms:
1 b) ⇒
