Question 75717: I need some help with some algebra word problems. I can't quite figure out the answers.
If you could help me i would greatly appreciate it.
The difference between the width and the length of a field is 12 m. Find its dimensions if a fence 160 m in length encloses it.
The length of a rectangle is found by doubling thw width and subtracting 3 m. Find its dimensions if the perimeter is 84 m.

Question 76284: Hi, I know I could get one question like this if someone could explain it to me - Three times the smaller of 2 numbers increased by 5 times the larger is 229. Four times the smaller decreased by 25 equals 3 times the larger. Find the numbers.
I started out with - x=bigger number, and y=smaller number
3y+5x=229 (first equation)
4y-25=3x (second equation)
How do you go on?

Question 76271: Hi everyone again, I know I already asked something similar to this already but something's not working out for me.
Four times the larger of 2 numbers decreased by 3 times the smaller is 152. Three times the larger increased by 5 times the smaller is 288. Find the numbers.
I started with x=larger number and y=smaller number
4x-3y=152 (1)
3x+5y=288 (2)
Now I'm stuck.

Question 79332: Hi, I've been trying to set up an appropriate system of equations for quite some time, and I've had no luck. The question is as follows;
The sum of the digits of a certain three digit number is nine. The sum of the hundreds and the tens digits is equal to the ones digit minus one. The number, divided by nine, equals three times the ones digit. What is the number? All I have so far is x+y+z=9. Could you show me how to set the problem up please?

Question 81848: Find two consecutive odd integers such that 5 times the first integer is 12 more than 3 times the second.
I don't even know how to sow my work to do this or even where to start. I have been muliplying 3's and 5's like a crazy lady, but there are so many numbers in this world!! hehehe
So far, I have only managed to guess at an expression for it as 5a - 3b = 12 which might make sense, but I don't think this is how they want you to figure it.
