Hey there!

We can solve systems two ways - substitution and elimination. It seems in this case that elimination is going to be easier.


Let's begin by multiplying the top equation by 3, and the bottom equation by 4:

3(5x - 4y = -24)

15x - 12y = -72


4(4x + 3y = 18)

16x + 12y = 72


Next, we'll add the two equations together to get rid of, or eliminate, the y variable and solve for the x variable:

(15x - 12y = -72) + (16x + 12y = 72)

31x = 0

x = 0


Next, we'll plug the value of the x variable into the top equation and solve for the y variable:

5(0) - 4y = -24

-4y = -24

y = 6


Therefore, x = 0 and y = 6.


Hope this helps!! :)

umka2103 [35]
2 digits number

x <100   because 2digit

x/10  ∈ { 1, 2, 3, 4, 5, 6, 7, 8, 9}

x/3  ∈ {1, 2, 3, 4, 5, 6, 7, 8, 9 }

max number divide by 10 is 90
max number divided by 3 is 99

because we know that numer is divided by 10 so our collections looks like:

{10, 20, 30, 40, 50, 60, 70, 80, 90}

we look from this collections only numbers witch will divided by 3:

30, 60, 90 = this is solutions

a) we need a natural number divided by 3 and 10 lower than 100
b) i need to use lenght of number and what numbers divides them
c) as above
d) baseball, 3 and 10, 3, 30,60,90
