Answer:
Simplifying
2x + -1(3y + -1(4x + -1(5y + -1(6x + -7y)))) = 0
2x + -1(3y + -1(4x + -1(5y + (6x * -1 + -7y * -1)))) = 0
2x + -1(3y + -1(4x + -1(5y + (-6x + 7y)))) = 0
Reorder the terms:
2x + -1(3y + -1(4x + -1(-6x + 5y + 7y))) = 0
Combine like terms: 5y + 7y = 12y
2x + -1(3y + -1(4x + -1(-6x + 12y))) = 0
2x + -1(3y + -1(4x + (-6x * -1 + 12y * -1))) = 0
2x + -1(3y + -1(4x + (6x + -12y))) = 0
Combine like terms: 4x + 6x = 10x
2x + -1(3y + -1(10x + -12y)) = 0
2x + -1(3y + (10x * -1 + -12y * -1)) = 0
2x + -1(3y + (-10x + 12y)) = 0
Reorder the terms:
2x + -1(-10x + 3y + 12y) = 0
Combine like terms: 3y + 12y = 15y
2x + -1(-10x + 15y) = 0
2x + (-10x * -1 + 15y * -1) = 0
2x + (10x + -15y) = 0
Combine like terms: 2x + 10x = 12x
12x + -15y = 0
Solving
12x + -15y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '15y' to each side of the equation.
12x + -15y + 15y = 0 + 15y
Combine like terms: -15y + 15y = 0
12x + 0 = 0 + 15y
12x = 0 + 15y
Remove the zero:
12x = 15y
Divide each side by '12'.
x = 1.25y
Simplifying
x = 1.25y
