Answer 1

The answers to your questions are
A)18,7,5,7
B)9,10
The answer is where the y value are the same so the answers are x where the y’s are the same.

Answer 2

The answers to your questions are

a) (18/7,5/7)

b) (9,10)

Explanation:

This can be determined by using various methods i.e substitution... , or eliminations method (just look those up) BUT !!!!

This question specifically askes you to do the problem using the graphing method... in other words for "a" graph y = 3x-7 and x+2y = 4

on the same graph paper , and determine where the lines cross... for "B" graph y=x+2 and y=2x+7..

I will do my best to graph the lines using demos

Technically the answer sked for is this chart 9see graphic #3)

so the answer is where the y values are the same

thus answer is (X. where the y's are the same)
