and the smaller number is
.
alan answer

Step-by-step explanation:

So let's make the two numbers "X" and "Y".

X + Y = 5

That's the very first line

let's take X as the bigger number and Y as the Smaller number.

3x + 2y = 28

now we have two equations and two unknowns.

We can also arrange the first equation to be as

X = 5 - Y

substitute this equation in the 2nd equation

3(5- Y) + 2Y = 28

15 - 3Y + 2Y = 28

-Y = 13

Y = -13

Substitute Value of Y in any equation to get X

X = 5 - (-13)

X = 18

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
