Answer:
x = 7
Step-by-step explanation:
[tex]- \frac{1}{3} (9x + 42) - 5x = - 70[/tex]
Multiply the terms in the bracket
We have
- 3x - 14 - 5x = - 70
- 8x - 14 = - 70
Using the addition property, add 14 to both sides
That's
- 8x + 14 - 14 = - 70 + 14
- 8x = - 56
Divide both sides by - 8
That's
[tex] \frac{ - 8x}{ - 8} = \frac{ - 56}{ - 8} [/tex]
We have the final answer as
x = 7
Hope this helps you
