Answer:
18 and 35
Explanation:
Let the two numbers be x and y, where x is the larger number and y is the smaller one.
We are given that the sum of these two number is 53, which can be written as:
--- (i)
Now, the larger number x is 1 less than 2 times the smaller number y. So we can write it as:
--- (ii)
Substituting the value of x in (i) to get:
![(2y-1)+y=53](https://img.qammunity.org/2019/formulas/mathematics/high-school/m3ttzoiwrmbelb5y67mgxdrlsuroe5qijw.png)
![3y=54](https://img.qammunity.org/2019/formulas/mathematics/high-school/6e1j8pqb6sz2mo9kn8ta7q7q2x2kbk6ts8.png)
![y=18](https://img.qammunity.org/2019/formulas/mathematics/middle-school/nvefax6plfkb35v10wulnsgd362wrnv0bx.png)
Put this value of y in (i) to find x:
![x+y= 53](https://img.qammunity.org/2019/formulas/mathematics/high-school/zi9y3qk1o1055wwuaa9pmyuivqfxfsv472.png)
![x=53-18](https://img.qammunity.org/2019/formulas/mathematics/high-school/46rdf92940n0v3w6goafdx9taahzjulj9v.png)
![x= 35](https://img.qammunity.org/2019/formulas/mathematics/high-school/b4yxwyqp3j64q0pwscgjvzrg0v82zwxdp0.png)
Therefore, the two numbers are 18 and 35.
