Question

xy+yz+zx=11 solve this equation

Answer 1

Answer:

Simplifying

xy + yz + zx = 11

Reorder the terms:

xy + xz + yz = 11

Solving

xy + xz + yz = 11

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1yz' to each side of the equation.

xy + xz + yz + -1yz = 11 + -1yz

Combine like terms: yz + -1yz = 0

xy + xz + 0 = 11 + -1yz

xy + xz = 11 + -1yz

Reorder the terms:

-11 + xy + xz + yz = 11 + -1yz + -11 + yz

Reorder the terms:

-11 + xy + xz + yz = 11 + -11 + -1yz + yz

Combine like terms: 11 + -11 = 0

-11 + xy + xz + yz = 0 + -1yz + yz

-11 + xy + xz + yz = -1yz + yz

Combine like terms: -1yz + yz = 0

-11 + xy + xz + yz = 0

so xy+xz+yz=11
