Question

15 POINTS!!! Solve 3(−3−3x)+4=−5. The solution is x=___

Answer 1

3(-3-3x)+4=-5

One solution was found :

x = 0
Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

3*(-3-3*x)+4-(-5)=0

Step by step solution :

Pull out like factors :

-3 - 3x = -3 • (x + 1)

Equation at the end of step 2 :

(-9 • (x + 1) + 4) - -5 = 0


Equation at the end of step 3 :

-9x = 0
Step 4 :

Solving a Single Variable Equation :

4.1 Solve : -9x = 0

Multiply both sides of the equation by (-1) : 9x = 0


Divide both sides of the equation by 9:
x = 0

One solution was found :

x = 0
