Explain your answer !!

Will give brainlst

x=-17

y=-2 2/3

Step-by-step explanation:

start with the second one and do substitution

x -6y=-1 add the -6y over to get x alone

x=6y-1 put this into first equation

2(6y-1)-15y=6 distribute

12y-2-15y=6 add like terms

-3y-2=6 add the -2 over

-3y=8 divide by -3

y=-2 2/3 put this back into the first equation that was solved for x

x=6(-2 2/3)-1 distribute

x=-17

what i would say the best answer is a. 40.5

x-3y=4
