Answer:
do u need help with the whole page?
Step-by-step explanation:
The answer is D. hope this helped :)
Y- -7-23
3x-4y= 30
3x-4(-7x-23)=30
3x+28x+92=30 -4 multiplied by -7x and -23 is a positive outcome not negative
31x+92=30
31x=30-92
31x=-62
x= -62/31
x= 2
I think this is the answer, I am a little rusty in the substitution method
