Question

3) -х – 3х + 10у – 5х – 8y

Answer 1

To simplify the given expression

`-x-3x+10y-5x-8y`

The first step is to order the like terms together, this means that you have to group the terms that contain the variable "x" together and the terms that contain the variable "y" together:

`(-x-3x-5x)+(10y-8y)`

Then you have to solve the calculations between them:

`-9x+2y`

The result is -9x+2y
