Question

Three times a number is the same as five more than twice the number

Answer 1

3x (three times a number) = (is the same as) 5 + (five more than) 2x (twice the number)

or, 3x = 5+2x
then subtract 2x from both sides: x = 5

Which should make sense, three times 5 is 15. 5 plus two times 5 is also 15.

Answer 2

Ok so first lets make the equation
3x=5+2x
we subtract 2 on each side
x=5
