3x+3 = -2x-12
find x
3x+3 = -2x-12
5x = -15
x = -3
thank you
To find the value of x in the equation 3x + 3 = -2x - 12, you can use algebraic steps to isolate the variable x.
1. Start by combining like terms on both sides of the equation.
Add 2x to both sides:
3x + 2x + 3 = -2x + 2x - 12
Simplify:
5x + 3 = -12
2. Next, move the constant term (in this case, 3) to the other side by subtracting 3 from both sides of the equation.
5x + 3 - 3 = -12 - 3
Simplify:
5x = -15
3. To isolate x, divide both sides of the equation by the coefficient of x, which is 5.
(5x) / 5 = (-15) / 5
Simplify:
x = -3
Therefore, the value of x in the equation 3x + 3 = -2x - 12 is x = -3.
