Multiply 2x-2y=10 by 2,
4x-4y=20,
given:4x-5y=17
y=3
pluck it in
2x-6=10
move the 6 to the right
2x=16
divide
x=8
y=3

Answer:

Step-by-step explanation:

A number to an exponent is the number times itself. A number to the "n"th power would be that number times itself "n" times.
This means that the fraction above could also be expressed as;

If these parameters, "a", "b", "c", and "d" are given a value, then one can solve this equation.
