Alan does 1/5 of the job in an hour. Gavin does 1/7 of the job in an hour
Together, 12/35 of the job should be done in an hour. In 
hours, the work should be done.
rate at 4 hours=*(normal speed-26)
To clarify, x=the normal rate
4 hours(normal rate-26)=(normal rate)
4(x-26)=x
x=96
Don't stress so much! I use to find these difficult as well! Everyone needs help sometime in their life!
<span>2x + 3y = 0:
</span>
1. Subtract 3y from both sides
2x = -3y
2. Divide both sides by 2
x = -3y over 2
****
1. Subtract 2x from both sides
3y = -2x
2. Divide both sides by 3
y = -2x over 3
-------------------------------------------------
8x + 9y = 18:
1. Subtract 9y from both sides
8x = 18 - 9y
2. Divide both sides by 8
x = 18 - 9y over 8
3. Factor out the common term 9
x = 9(2 - y) over 8
****
1. Subtract 8x from both sides
9y = 18 - 8x
2. Divide both sides by 9
y = 18 - 8x over 9
3. Factor out the common term 2
y = 2(9-4x) over 9
