Answer:
5
Step-by-step explanation:
120/2=60/5=12
<span>We move all terms to the left:
-840-(-15(-7x+7))=0
</span>We calculate terms in parentheses: -(-15(-7x+7)), so:
-15(-7x+7)
We multiply parentheses
105x-105
Back to the equation:
<span>
-(105x-105)
</span>
<span>We get rid of parentheses
-105x+105-840=0
We add all the numbers together, and all the variables
-105x-735=0
We move all terms containing x to the left, all other terms to the right
-105x=735
x=735/-105
x=-7

Answer:
x > - 8 or x < 2
Step-by-step explanation:
Given
- 8 < 2(x + 4) or - 3x + 4 > x - 4
Solve each part separately
- 8 < 2(x + 4) ← divide both sides by 2
- 4 < x + 4 ( subtract 4 from both sides )
- 8 < x , thus
x > - 8
OR
- 3x + 4 > x - 4 ( subtract x from both sides )
- 4x + 4 > - 4 ( subtract 4 from both sides )
- 4x > - 8
Divide both sides by - 4, reversing the symbol as a result of dividing by a negative quantity
x < 2
Solution is x > - 8 or x < 2
