Question

Hi I need help with 4 problems you don't have to answer all of them just the ones you think you might know and I need to know how to do it. The questions are below:)

1. -3x + 10
2. 4x +8
3. -1 - 4x
4. 7 -5x

Answer 1

1. -30x 2. 12x 3. x 4. 2x

Explanation:

i believe the way your learning is that you have to add or subtract both numbers and then add the letter next to the answer. number 3 is just x because -1- 4x = 0 and just add the x.
