Question

Which of the following is equivalent to 10 – 4x < 50?

Answer 1

Answer  x = -10

Step-by-step explanation:

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

                     10-4*x-(50)=0 

STEP1:Pulling out like terms

 1.1     Pull out like factors :

   -40 - 4x  =   -4 • (x + 10) 

Equation at the end of step1:

STEP2:

Equations which are never true:

 2.1      Solve :    -4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

 2.2      Solve  :    x+10 = 0 

 Subtract  10  from both sides of the equation : 

                      x = -10

One solution was found :

 x = -10
