To solve for x, we need to isolate the variable x on one side of the equation.
Starting with the given equation:
3x - 3 = 6x + 18
First, let's simplify the equation by combining like terms:
3x - 6x = 18 + 3
Now, simplify further:
-3x = 21
To isolate x, divide both sides of the equation by -3:
-3x / -3 = 21 / -3
This yields:
x = -7
Therefore, the value of x that satisfies the equation is x = -7.
solve for x: 3x-3=6x+18
