To solve for x, we can first simplify the equation:
3x - 3 = 6x - 18
By adding 3x to both sides:
-3 = 3x - 18
Next, add 18 to both sides:
15 = 3x
Finally, divide by 3 to solve for x:
x = 5
Therefore, the solution is x = 5.
3x - 3 = 6x - 18
By adding 3x to both sides:
-3 = 3x - 18
Next, add 18 to both sides:
15 = 3x
Finally, divide by 3 to solve for x:
x = 5
Therefore, the solution is x = 5.
-7
2
-6
9
1. x = -7
3(-7) - 3 = 6(-7) - 18
-21 - 3 = -42 - 18
-24 ≠-60 (false)
2. x = 2
3(2) - 3 = 6(2) - 18
6 - 3 = 12 - 18
3 ≠-6 (false)
3. x = -6
3(-6) - 3 = 6(-6) - 18
-18 - 3 = -36 - 18
-21 ≠-54 (false)
4. x = 9
3(9) - 3 = 6(9) - 18
27 - 3 = 54 - 18
24 = 36 (false)
Thus, none of the given options satisfy the equation 3x - 3 = 6x - 18.
Let's try x = -6
3(-6) - 3 = 6(-6) - 18
-18 - 3 = -36 - 18
-21 = -54
Let's try x = 2
3(2) - 3 = 6(2) - 18
6 - 3 = 12 - 18
3 = -6
Since -21 is closer to -18 than 3 is to -6, the closest approximate solution would be x = -6.
4x + 8 = 3x - 10
By subtracting 3x from both sides:
4x - 3x + 8 = -10
Simplify:
x + 8 = -10
Subtract 8 from both sides:
x = -18
Therefore, the solution is x = -18.
