33 * 3 + 3/3 = 100
I do not believe u have to use all of the operations because it says " at most once ".
It looks like the differential equation is

Multiply both sides by 1/(<em>x</em> + 1) :

The left side is now a derivative of a product,

Integrate both sides with respect to <em>x</em> :

Solve for <em>y</em> :

Answer:
x= 3
y = 0
Step-by-step explanation:
•Add the two equations to cancel out +6x and -6x
•Find the value of y
•Substitute the value of y into equation 1 to find the value of x.
