How about this:
The book has 712 pages. Ted has already read 408 pages, so he has 304 left to read.
712 - 408 = 304
First abswer is 51700
Sexond answer is 10340
To make it much easier, it should be converted to the slope-intercept form
y = mx + bTo do so, 14x + 34y = 1 turns to:
34y = -14x + 1Divide both sides by 34:

Simplified:
Answer: 
Here is the graph:
First subtract the 7 from both sides and that would equal 2x+9=2x then subtract 2x and the answer is 9
