1.5(x+1.2y)+2(1.2x+1.2y)=

Solution for 1.5(x+1.2y)+2(1.2x+1.2y)= equation:

Simplifying
1.5(x + 1.2y) + 2(1.2x + 1.2y) = 0
(x * 1.5 + 1.2y * 1.5) + 2(1.2x + 1.2y) = 0
(1.5x + 1.8y) + 2(1.2x + 1.2y) = 0
1.5x + 1.8y + (1.2x * 2 + 1.2y * 2) = 0
1.5x + 1.8y + (2.4x + 2.4y) = 0

Reorder the terms:
1.5x + 2.4x + 1.8y + 2.4y = 0

Combine like terms: 1.5x + 2.4x = 3.9x
3.9x + 1.8y + 2.4y = 0

Combine like terms: 1.8y + 2.4y = 4.2y
3.9x + 4.2y = 0

Solving
3.9x + 4.2y = 0

Solving for variable 'x'.

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

Add '-4.2y' to each side of the equation.
3.9x + 4.2y + -4.2y = 0 + -4.2y

Combine like terms: 4.2y + -4.2y = 0.0
3.9x + 0.0 = 0 + -4.2y
3.9x = 0 + -4.2y
Remove the zero:
3.9x = -4.2y

Divide each side by '3.9'.
x = -1.076923077y

Simplifying
x = -1.076923077y
