Question

In a 2 digit number the unit digit is 4 times the tens digit and the sum of the digits is 60. Find the number. ​

Answer 1

Answer:

i think im wrong but these are the steps

Step-by-step explanation:

let tens digit=x

ones digit=4x

x+4x=60

5x=60

x=60/5

x=tens digit=12

ones=4x=4*12=48

Answer 2

x is a two digit number with tens digit a and units digit b:

10a+b=x

The units digit is 4 times the tens digit:

b=4a

The sum of a and b is 10:

a+b=10

Simple subsitution:

a+4a=5a=10

a=10/5=2

Since the sum of a and b is 10:

b=10−a=10−2=8

x=10a+b

=10×2+8

=20+8

=28

∴ x = 28
