Class 9

Answer 1

Answer:

Simplifying

2x + -4y + -14 = 0

Reorder the terms:

-14 + 2x + -4y = 0

Solving

-14 + 2x + -4y = 0

Solving for variable 'x'.

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

Add '14' to each side of the equation.

-14 + 2x + 14 + -4y = 0 + 14

Reorder the terms:

-14 + 14 + 2x + -4y = 0 + 14

Combine like terms: -14 + 14 = 0

0 + 2x + -4y = 0 + 14

2x + -4y = 0 + 14

Combine like terms: 0 + 14 = 14

2x + -4y = 14

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

2x + -4y + 4y = 14 + 4y

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

2x + 0 = 14 + 4y

2x = 14 + 4y

Divide each side by '2'.

x = 7 + 2y

Simplifying

x = 7 + 2y
