Please help me this is a test that is important

implifying

2x + 2y = 4xy

Solving

2x + 2y = 4xy

Solving for variable 'x'.

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

Add '-4xy' to each side of the equation.

2x + -4xy + 2y = 4xy + -4xy

Combine like terms: 4xy + -4xy = 0

2x + -4xy + 2y = 0

Add '-2y' to each side of the equation.

2x + -4xy + 2y + -2y = 0 + -2y

Combine like terms: 2y + -2y = 0

2x + -4xy + 0 = 0 + -2y

2x + -4xy = 0 + -2y

Remove the zero:

2x + -4xy = -2y

Combine like terms: -2y + 2y = 0

2x + -4xy + 2y = 0

Factor out the Greatest Common Factor (GCF), '2'.

2(x + -2xy + y) = 0

Ignore the factor 2.

Subproblem 1

Set the factor '(x + -2xy + y)' equal to zero and attempt to solve:

Simplifying

x + -2xy + y = 0

Solving

x + -2xy + y = 0

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

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

x + -2xy + y + -1y = 0 + -1y

Combine like terms: y + -1y = 0

x + -2xy + 0 = 0 + -1y

x + -2xy = 0 + -1y

Remove the zero:

x + -2xy = -1y

The solution to this equation could not be determined.

This subproblem is being ignored because a solution could not be determined.

The solution to this equation could not be determined.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
