SOLUTION:
Question 4 -
- 2x + 5 = - 13 + x
- 2x - x = - 13 - 5
- 3x = - 18
x = - 18 / - 3
x = 18 / 3
x = 6
Question 6 -
2x + 7 = - 2 - x
2x + x = - 2 - 7
3x = - 9
x = - 9 / 3
x = - 3
Question 8 -
2x + 12 = - 6 - x
2x + x = - 6 - 12
3x = - 18
x = - 18 / 3
x = - 6
Hope this helps! :)
Have a lovely day! <3
