Answer: 4ab+10b
2.5ab+14b+1.5b-4
4ab+14b-4b
4ab+10b
Answer:
Infinitely many solutions.
Step-by-step explanation:
x-2y=-3
14y-7x=21
-------------
simplify 14y-7x=21 into 2y-x=3
x-2y=-3
2y-x=3
--------------
x=2y+(-3)
x=2y-3
2y-(2y-3)=3
2y-2y+3=3
0+3=3
infinitely many solutions
The y intercept is where the line hits the verticals line of the graph. Hope this helps!
