Solution - Linear equations with one unknown

x = - \frac{21}{4} = - 5.250

x=-21/4=-5.250

Step by Step Solution

Step by step solution :

Step 1 :

Solving a Single Variable Equation :

1.1      Solve  :    4x+21 = 0

Subtract 21 from both sides of the equation :
                      4x = -21
Divide both sides of the equation by 4:
                     x = -21/4 = -5.250

One solution was found :

x = -21/4 = -5.250
