Spiral Review Solve the equation. 3(x - 1) = 27 – 2x Enter the correct answer in the box be

x = 6

Step-by-step explanation:

                                              3(x - 1) = 27 - 2x

Multiply out the brackets:     3x - 3 = 27 - 2x

Collect like terms:               3x + 2x = 27 + 3

                                                    5x = 30

Divide both sides by 5:                 x = 6

We have the following expression:
 S = 6x ^ 2
 We must clear x from the equation.
 For this, we follow the following steps:
 Step 1)
 Pass 6 to divide:
 S / 6 = x ^ 2
 Step 2)
 Square root on both sides:
 +/- root (S / 6) = x
 Step 3)
 Multiply numerator and denominator by 6:
 x = + / - root (6S / 6 * 6)
 Step 4)
 Rewrite expression:
 x = + / - root (6S / 36)
 Step 5)
 Take root to denominator:
 x = + / - (root (6S)) / 6
 
 x = + / - (root (6S)) / 6
