We multiply 1/2 by 3/3.
1 x 1 y.
The biggest problem is that x is in the denominator.
If the two fractions are added to give one term, then we can invert both sides.
Subtract 1 x 1 x from both sides of the equation.
To write 1 y 1 y as a fraction with a common denominator, multiply by x x x x.
We multiply 1/y by x/x.
Eg x = 2 and y = 3 1/2 + 1/3 = ?
We multiply 1/3 by 2/2.
In school you were taught that 1/x+y is not the same as 1/x + 1/y, but for which x and y is it actually true?
X = 1 and y = 2 explanation:
Solve for y (1/x)+ (1/y)=1.
Divide both sides by 1 − y.
1 x = z + y yz.
Swap sides so that all variable terms are on the left hand side.
X times y is the common denominator.
Add 1 to both sides.
Take the cube root of each side of the equation to set up the solution for x x.
Multiply 1 x 1 x and y y y y.
We multiply 1/x by y/y.
