A number is 6 more than two times another number. Sum of the two number is 24. find the number ??

Question

The answer of this question is 6,18. And this question is from Linear equations.. please give right answer . Because teacher takes test ... Pleasee fast

Answer 1

Suppose the number we need to find out is y and another number is x.

First equation:

The number is 6 more than 2 times another number that is

y = 2x + 6

Second equation:

Sum of two number is 24

x + y = 24

x = 24 - y

We need to find the value for y, so we are substituting value of x from second equation to x in first

y = 2(24 - y) + 6

y = 48 - 2y + 6

y + 2y = 48 + 6

3y = 54

y = 18

The number is 18 whereas another number is 6 which adds up to 24.
