In this system of equations, which variable would it be easiest to solve for?

x + 3 y = 13.
3 x + 2 y = 25.

x=7& y= 2

Step-by-step explanation:

x+3y=13

3x+2y=25

Using elimination method

We have

3× x+3y=13I

1×3x+2y=25ii

3x+9y=39

3x+2y=25

7y=14

Divide through by 7

y=2

Substitute for y in equation i

x+3(2)=13

x+6=13

x=7

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
