<em>3(3x - 3) = 10x</em>
<em>9x - 9 = 10x</em>

<em>x = - 9</em>
Answer:
1. x = 11,
2. w = -7,
3. x = -5
4. x = -5
5. x = -9
Step-by-step explanation:
1. x-6 = -3+8
x - 6 = 8 -3
x - 6 = 5
Adding 6 to both sides:
x - 6 + 6 = 5 + 6
x = 11
2. 3w - 8w = 35
3w - 8w = 35
-5w = 35
Divide both sides by -5
-5w/-5 = 35/-5
w = -7
3. - 4 x - 4 x = 44 - 4
- 4 x - 4 x = 44 - 4
-8x = 40
Divide both sides by -8
-8x/-8 = 40/-8
x = -5
4. 5 -8 = 3x +2 - 2x
Collecting like terms and rearranging equation
3x - 2x = 5 - 8 - 2
x = 5 - 10
x = -5
5. 3(3x - 3) = 10x
3(3x - 3) = 10x
Expanding and removing parenthesis
9x - 9 = 10x
Collecting like terms and rearranging equation
10x - 9x = -9
x = -9
