Answer:

x=18

Step-by-step explanation:

hope it helps :)

Rearrange:

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

                    2/3*x-(12)=0

Step by step solution :

STEP

1

:

           2

Simplify   —

           3

Equation at the end of step

1

:

  2        

 (— • x) -  12  = 0

  3        

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

         12     12 • 3

   12 =  ——  =  ——————

         1        3  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2x - (12 • 3)     2x - 36

—————————————  =  ———————

      3              3  

STEP

3

:

Pulling out like terms

3.1     Pull out like factors :

  2x - 36  =   2 • (x - 18)

Equation at the end of step

3

:

 2 • (x - 18)

 ————————————  = 0

      3      

STEP

4

:

When a fraction equals zero

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 2•(x-18)

 ———————— • 3 = 0 • 3

    3    

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  2  •  (x-18)  = 0

Equations which are never true:

4.2      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.3      Solve  :    x-18 = 0

Add  18  to both sides of the equation :

                     x = 18

One solution was found :

x = 18

Three times a number plus 12 minus 5 times the same number is 22. What is the number?
JulijaS [17]
3x + 12 - 5x = 22
-2x + 12 = 22
-2x = 10
x = -5

Write the equation out, x is going to be your unknown number.
Combine like terms.
We have to isolate x, so get rid of the 12 by subtracting it from both sides of the equation.
Divide by -2.
