Question 194145: The perimeter of a rectangle is six times the width. If the length were increased by 4 inches and the width were increased by 7 inches, then the perimeter would be 160 inches. What is the width?
P = 2l + 2w
160 = (2l + 4) +(2w +7) When I substitute, it is just a mess.

Question 197443: Hi!
I am having trouble putting the following equation into proper form. My assignment was to create two equations that would fit the intergers 4,9. I chose for my first equation: 2x+3y=35. The other equation and the one I am having trouble with is 52=4x-4y. I thought when I put the second equation into the form ax+by=c my answer would be 4x+4y=52. I am wrong. Can you please help me? Thank you in advance. Lynne
