Answer:
x^2-7x+2x-14 or x squared minus seven x plus two x minus fourteen
Step-by-step explanation:
(x+2)*(x-7)= x^2-7x+2x-14
First: x^2
Outer: -7x
Inner: 2x
Last: -14
Multiply the first equation by 3
21x+15y=-6
Add this to the second equation
21x+15y=-6
-21x-15y=6
0+0=0
True
Final answer: Infinitely Many Solutions (they are coinciding lines)
