when 12 is added to a certain number and the result is multiplied by 4. the final result is 60.find the number.

Work Shown:

x = some unknown number

x+12 = adding 12 to the unknown number

4(x+12) = multiplying the previous sum by 4

4(x+12) = 60 set this equal to the desired result we want

Now solve for x. We will undo the steps done above to isolate x

4(x+12) = 60

x+12 = 60/4 divide both sides by 4 to undo "multiply by 4"

x+12 = 15

x = 15-12 undo "add 12" by subtracting 12 from both sides

x = 3

The unknown number is 3

add 12 to it to get 3+12 = 15

multiply that sum by 4 to get 15*4 = 60

Answer is confirmed.

The number is 3

Step-by-step explanation:

Let x be the number

Add 12

(x+12)

Then multiply by 4

4(x+12)

This is equal to 60

4(x+12) = 60

Divide each side by 4

4(x+12)/4 = 60/4

x+12 = 15

Subtract 12 from each side

x+12-12 = 15-12

x = 3

no
