Answer:
should be the last one 5-i8
For the second equation solve for x and you will get x= 2y-8 plug that in for the first equation and you will have -24=12 making it no solutions. And for b i would say that y is -2times bigger than x for both equations so that will guarantee both will cancel
Answer:
x= 70
Step-by-step explanation:
The equation is: x/7-12= -2
First, do inverse operations. Do = +12 on each side to get rid of 12
Now: x/7=10
Multiply 7 on each side
Now: x=70
Hope this helped!!! :D
