You multiply a number by 3 subtract 6 then add 2 the results is 20 what's the number
e-lub [12.9K]

You multiply a number by 3 subtract 6 then add 2 the results is 20

what's the number​ ?

Let the number = x

multiply a number by 3

so, it becomes 3x

subtract 6 , so, 3x - 6

then add 2

so, 3x - 6 + 2

The result will be 20

So,

3x - 6 + 2 = 20

solve for x

3x - 4 = 20

Add 4 to both sides

3x - 4 + 4 = 20 + 4

3x = 24

Divide both sides by 3

3x/3 = 24/3

So,

x = 8
