Answer:

Explanation:

Simplifying

6x + 4y = 6

Solving

6x + 4y = 6

Solving for variable 'x'.

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

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

6x + 4y + -4y = 6 + -4y

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

6x + 0 = 6 + -4y

6x = 6 + -4y

Divide each side by '6'.

x = 1 + -0.6666666667y

Simplifying

x = 1 + -0.6666666667ySimplifying

6x + 4y = 6

Solving

6x + 4y = 6

Solving for variable 'x'.

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

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

6x + 4y + -4y = 6 + -4y

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

6x + 0 = 6 + -4y

6x = 6 + -4y

Divide each side by '6'.

x = 1 + -0.6666666667

Simplifying

x = 1 + -0.6666666667

Simplifying

2x + 5y = 9

Solving

2x + 5y = 9

Solving for variable 'x'.

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

Add '-5y' to each side of the equation.

2x + 5y + -5y = 9 + -5y

Combine like terms: 5y + -5y = 0

2x + 0 = 9 + -5y

2x = 9 + -5y

Divide each side by '2'.

x = 4.5 + -2.5y

Simplifying

x = 4.5 + -2.5y
