Sagot :

Explanation

To solve the question we will have to set up a simultaneous equation

If x represents the larger number

y represents the smaller number, then

The sum of the two numbers is 35

[tex]Equation\text{ 1: x+y=35}[/tex]

The larger number is one less than three times the smaller number.

[tex]Equation\text{ 2: }x=3y-1[/tex]

So, we will solve the equation using the substitution method

Thus, we will substitute x = 3y -1 into equation 1

[tex]\begin{gathered} 3y-1+y=35 \\ 3y+y-1=35 \\ 4y-1=35 \\ 4y=35+1 \\ 4y=36 \\ \\ y=\frac{36}{4} \\ \\ y=9 \end{gathered}[/tex]

The smaller number is 9

The larger number will be

[tex]\begin{gathered} x+y=35 \\ x=35-y \\ x=35-9 \\ x=26 \end{gathered}[/tex]

The larger number is 26

The answers are 9 and 26
