Question

the difference between the digits in a two-digit numeral is 3. The units digit is twice the tens digit. Find the numeral.

Answer 1

we could write the first words in math as \(x-y=3\) i.e. the difference is 3

Answer 2

then the second one means \(y=2x\)

Answer 3

oh that isn't going to work, lets say
\(y-x=3\) and \(y=2x\)

Answer 4

that makes \(2x-x=3\) or \(x=3\) and so \(y=6\) making your number \(36\)

Answer 5

Let the tens digit be x.

Difference is 3.

Units digit is twice the tens digit so..

x - 2x = 3

-x = 3

x = -3

Tens digit is -3 and one digit -6.

Number is -36.

Answer 6

How do ypu the equation?
