How do you solve x+(2x + 40) + (3x - 50) = 15002
alina1380 [7]
1. Take away the parentheses. x+2x+40+3x-50=15002

2. Add the X’s together.
x+2x+3x= 6x —> 6x+40-50=15002

3. Subtract 50 from 40.
40-50= -10 —> 6x-10=15002

4. Move -10 to the right hand side to make it positive.
6x=15002+10

5. Add 15002 and 10 together.
6x=15012
