2x - 3y = 16
3x + 2y = 11
solve the system of equations.
a) (151 2 ,5)
b) (5,-2)
c) (5, 4)
d) (-1, -6)

B) (5,-2)

Step-by-step explanation:

we have the equations:

We multiply the first equation by 3:

i will call this equation 1.

and we multiply the second equation by 2:

i will call this equation 2.

Now we subtract equation 2 from equation 1:

this is:

which gives:

and now that we know that we substitute this value in any of the original equations to find

using

we have:

so

the answer is which is option B.

1st eq: 2x -3y =16

2nd eq: 3x +2y = 11

2(5) -3(-2) = 10+6 =16

3(5) +2(-2) = 15-4 = 11

 answer is B
