Subtract 3 from each side:
3x = -30
Divide each side by 3 :
x = -10
3 x + 3 = − 27 3 x = − 27 − 3 = − 30 x = − 30/3 = − 10 T h u s , x = − 10
The value of x in the equation 3x + 3 = -27 is -10. We find this by subtracting 3 from both sides and then dividing by 3. The solution is confirmed by substituting -10 back into the original equation.
