Which statement correctly explains how andre could find the solution to the following system of linear equations using elimination?
8s-9t=15
7s-2t=12

See explanations

Step-by-step explanation:

The first equation is:

The second equation is

To eliminate t, Andre can multiply the first equation by -2  and the second equation by 9 to obtain:

When he adds the two equations he gets:

If Andre wants to eliminate s, he can multiply the first equation by 7 and multiply the second equation by 8 to get:

He then subtracts to get:

There are other few ways Andre can do this.

Since you have not provided the options, we can tell exactly what Andre did.

ik this stuph and i am smart donkey

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
