Simplifying
2x + (5x + -3y) = 0
Remove parenthesis around (5x + -3y)
2x + 5x + -3y = 0
Combine like terms: 2x + 5x = 7x
7x + -3y = 0
Solving
7x + -3y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
7x + -3y + 3y = 0 + 3y
Combine like terms: -3y + 3y = 0
7x + 0 = 0 + 3y
7x = 0 + 3y
Remove the zero:
7x = 3y
Divide each side by '7'.
x = 0.4285714286y
Simplifying
x = 0.4285714286y
