21 times a number increased

by 6 is the same as 60 more
than 3 times the number Find the
number

Answer 1

3

Explanation:

21x + 6 = 3x + 60 subtract 3x from both sides

(21x-3x) + 6 = 60

18x + 6 = 60 subtract 6 from both sides

18x= 60-6

18x= 54 divide by 18

x =3

Answer 2

Answer: the number is 3

Explanation:

This can be written mathematically as

21y + 6 = 60 + 3y

21y - 3y = 60 - 6

18y = 54

y = 54/18 = 3
