Question

How do you solve `25-4x+6x+15`?

Answer 1

Use the Order of Operation

Explanation:

The order of operations is PEMDAS Think about it this way
If you get hurt in PE call an MD ASap

There are no parenthesis or exponents so start with o and Division going from left to right ( Remember that MD is one person so do Multiplication and Division at the same time)
there is no Multiplication and Division so go on to Addition and Subtraction.

Start by adding ( - 4x + 6x)

`25 ( -4x +6x ) + 15 = 25 + 2x + 15`

Use the communicative property to group the like terms.

`25 + 2x + 15 = ( 25 + 15) + 2x`

`( 25 + 15 + 2x = 40 + 2x`

This can be reduced to

`2 ( 20 + x )`

It is not really possible to solve this because there is no equal sign

Answer 2

`2x+40`

Explanation:

We have the following:

`color(steelblue)(25)color(purple)(-4x+6x)+color(steelblue)(15)`

We can combine our variables terms to get `color(purple)(2x)`, and our constants to get `color(steelblue)(40)`. Putting it all together, we get

`2x+40`

Hope this helps!
