262,144,000,000 is your answer to your question
We have such system of eq

First lets solve second eq
7x=21 /:7 divide both sides by 7
x=3
Now we can substitute it to first equation
9x-2y=19
9*3-2y=19
27-2y=19 /-27 subtract 27 both sides
-2y=-8 /:(-2) divide both sides by -2
y=4 - its the answer
How ever many times it goes into 100
-10 can be plotted in the far left side
Start with -1,-2,-3,-4,-5,-6,-7,-8,-9 then -10
