Question

Find an expression which represents the sum of (4x + 1) and (-9x + 6) in

simplest terms.

Answer 1

`-5x+7`

Explanation:

Given: Two expressions are
`(4x+1),(-9x+6)`

To find: sum of the given expressions in simplest terms

Solution:

A variable is a term that takes various numerical values and a constant is a term that takes a fixed numerical value.

Consider
`(4x+1)+(-9x+6)`

Here, solve
`(4x-9x),(1+6)`

`4x-9x=(4-9)x=-5x\\1+6=7`

Therefore,

`(4x+1)+(-9x+6)=(4x-9x)+(1+6)=-5x+7`
