Question

A number is 11 less than 3 times another number. The sum of the numbers

Answer 1

Step-by-step explanation:

this is simple use it and enjoy

Answer 2

Step-by-step explanation:

Let x be the first number

Let y be the 2nd number

given,

$x = 3y - 11 \\ x - 3y = - 11$

as equation 1

and

$x + y = 25$

as equation 2.

Now we will use elimination method to solve for simultaneous equations.

We will use equation 1 - equation 2 to eliminate x to solve for y.

$x - x - 3y - y = - 11 - 25 \\ - 4y = - 36 \\ y = - 36 \div - 4 \\ = 9$

Substitute y into equation 2.

$x + 9 = 25 \\ x = 25 - 9 \\ = 16$

The numbers are 9 and 16.
