Sorry this is the answer to the 2nd question. Using the straight lines x + y = 56 and y = 3x, then they would intersect at x = 14 and y = 42

*March 25, 2010*

**Math 116 algebra**

I think this is right but I'm not sure on this part of your problem. from part a, x + y = 56, then at x = 0, y = 56. Therefore y-intercept = 56 at y = 0, x = 56. Therefore x-intercept = 56 from part b, y = 3x, then This is a straight line, passing through the origin ...

*March 25, 2010*

**Math 116 algebra**

well the 4 came because it says y = 3 times as many as x so for y to be 3 times as many as x there has to be 4 parts of 56 1 part is x and the remaining 3 are y. Does that help?

*March 25, 2010*

**Math 116 algebra**

I guess you could write it x+y=56 4x=56 56/4=x x=14 14+y=56 56-14=y y=52 I'm not sure how your teacher would want you to show your work. This way might be the simplest form

*March 25, 2010*

**Math 116 algebra**

x+y=56 x+3x=56 56/4= 14 x=14 56-14=42 y=42 check 14+42=56 or 14+(14*3)=56

*March 25, 2010*

**Math 116 algebra**

I don't think so The second part is giving you a way to solve the problem. so if you find out whay y is then you can find out what x is.

*March 25, 2010*

**Math 116 algebra**

because now you have 3x=y

*March 25, 2010*

**Math 116 algebra**

I think it would be x+3x=56

*March 25, 2010*

I think it would be x+y=56
