Question

if the sum of a number and 6 is tripled, the result is four less than twice the number. Find the number

Answer 1

"if the sum of a number and 6" can be written this way: x+6

Answer 2

"the result is" means you stick in the equals sign: x+6 =

Answer 3

"four less than twice the number" is this: 2x-4.

Answer 4

So the whole equation is x+6=2x-4
Now solve that for x. Can you do that?

Answer 5

5 ?

Answer 6

x + 6 = 2x - 4
subtract x from both sides:
6 = x - 4
add 4 to both sides:
10 = x or x = 10.

-22
