Question

A number is multiplied by 6 and then 4 is added​

Answer 1

You mean;

A number is multiplied by 6, then 4 is added to the product. The result is 82. What is the number?

So, lets call the number 'x'

6 multiplied by x plus 4 equals 82

So,

6x + 4 = 82

Now subtract 4 from both sides of the equation:

6x + 4 - 4 = 82 - 4

6x = 78

Now divide both sides of the equation by 6 to find the value of 'x':

(6x)/6 = 78/6

x = 13

So the number you wanted to find is 13
