Question

If 68 is added to a number, the result is 38 less than three times the number. Find the number.

Answer 1

53

Explanation:

Let the number be x.

"If 68 is added to a number" ➮ x +68

" 38 less than 3 times the number" ➮ 3x -38

Write an equation down:

x +68= 3x -38

Bring x terms to 1 side, constant to the other:

3x -x= 68 +38

Simplify:

2x= 106

÷2 on both sides:

x= 53

Thus, the number is 53.
