2.2(x+3.5y)+4(3.5x+1.5y)=

Solution for 2.2(x+3.5y)+4(3.5x+1.5y)= equation:

Simplifying
2.2(x + 3.5y) + 4(3.5x + 1.5y) = 0
(x * 2.2 + 3.5y * 2.2) + 4(3.5x + 1.5y) = 0
(2.2x + 7.7y) + 4(3.5x + 1.5y) = 0
2.2x + 7.7y + (3.5x * 4 + 1.5y * 4) = 0
2.2x + 7.7y + (14x + 6y) = 0

Reorder the terms:
2.2x + 14x + 7.7y + 6y = 0

Combine like terms: 2.2x + 14x = 16.2x
16.2x + 7.7y + 6y = 0

Combine like terms: 7.7y + 6y = 13.7y
16.2x + 13.7y = 0

Solving
16.2x + 13.7y = 0

Solving for variable 'x'.

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

Add '-13.7y' to each side of the equation.
16.2x + 13.7y + -13.7y = 0 + -13.7y

Combine like terms: 13.7y + -13.7y = 0.0
16.2x + 0.0 = 0 + -13.7y
16.2x = 0 + -13.7y
Remove the zero:
16.2x = -13.7y

Divide each side by '16.2'.
x = -0.8456790123y

Simplifying
x = -0.8456790123y
