Question

“Use the properties to rewrite this expression with the fewest terms possible:3+7(x - y) + 2x - 5y”

Answer 1

`-5y+2x+7(x-y)+3`

Expanding 7(x - y) in the above expression gives

`-5y^{}+2x+7x-7y+3`

adding the like terms (2x+ 7x) and (-5y-7y) gives

`(-5y-7y)+(2x+7x)+3`
`\rightarrow\textcolor{#FF7968}{-12y+8x+3.}`

The last expression is the simplest form we can convert our expression into.
