write word problem into numerical equation and solve

I have four questions here:

1) The length of a rectangel is 3 more than twice its width. If the perimeter of the rectangle is 96 feet, find the length of the rectangle.

2) You collected $175 the second week of a charity drive. This amount was $35 more than you collected the first week. How much did you collect inthe two weeks?

3) Seven less than twice a number is the same as 9 more than 4 times the number. Find the number.

4) You have $1.80 in nickels, dimes and quarters. You have twice as many quarters as nickels. The number of dimes is one more than the number of nickels and quarters put togethers. Pick the three equations that can be made from this scenario:

a. 5N + 10D + 25Q = 180

b. 0.05N + 0.1D + 0.25 Q = 180

c. Q=2N

d. N=2Q

e. D=N + Q + 1

f. D + 1 = N + Q
