Question

1.)(4n+8)+(5m+3)2.) (7c+7)+(6m-4)+(8n+3)3.) (8y+5)+(6m+9y)+(-4-3m)4.) (5x+7)+(-6x+9)

Answer 1

Simplify the following;

`\begin{gathered} (1)4n+8+5m+3 \\ =4n+8+3+5m \\ =4n+11+5m \\ (2)7c+7+6m-4+8n+3 \\ =7c+7-4+3+6m+8n \\ =7c+6+6m+8n \\ (3)8y+5+6m+9y-4-3m \\ =8y+9y+5-4+6m-3m \\ =17y+1+3m \\ (4)5x+7-6x+9 \\ =5x-6x+7+9 \\ =-x+16 \\ =16-x \end{gathered}`

So, to simplify these kind of expressions basically means to collect like terms where applicable.
