Question 86731
The variable x is 4 less than the variable y.
x=y-4
-------------

 1. If the variable t is multiplied by 5, the result is equal to the variable R.
5t=R
----------

 2. If 3 is subtracted from the product of the variables x and y, the result is equal to 4 times the variable z.
(xy)-3 = 4z
-------------

 3. The quotient of the variable x with the variable y is 2 more than 0.7 of the variable z.	
(x/y)=0.7z+2
