Answer 1

Respuesta:

hla

Explicación paso a paso:

Simplifying

2x + -1y + 4 = 0

Reorder the terms:

4 + 2x + -1y = 0

Solving

4 + 2x + -1y = 0

Solving for variable 'x'.

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

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

4 + 2x + -4 + -1y = 0 + -4

Reorder the terms:

4 + -4 + 2x + -1y = 0 + -4

Combine like terms: 4 + -4 = 0

0 + 2x + -1y = 0 + -4

2x + -1y = 0 + -4

Combine like terms: 0 + -4 = -4

2x + -1y = -4

Add 'y' to each side of the equation.

2x + -1y + y = -4 + y

Combine like terms: -1y + y = 0

2x + 0 = -4 + y

2x = -4 + y

Divide each side by '2'.

x = -2 + 0.5y

Simplifying

x = -2 + 0.5y
