Solution for (x-y)(3x-4y)= equation:


Simplifying
(x + -1y)(3x + -4y) = 0

Multiply (x + -1y) * (3x + -4y)
(x(3x + -4y) + -1y * (3x + -4y)) = 0
((3x * x + -4y * x) + -1y * (3x + -4y)) = 0

Reorder the terms:
((-4xy + 3x2) + -1y * (3x + -4y)) = 0
((-4xy + 3x2) + -1y * (3x + -4y)) = 0
(-4xy + 3x2 + (3x * -1y + -4y * -1y)) = 0
(-4xy + 3x2 + (-3xy + 4y2)) = 0

Reorder the terms:
(-4xy + -3xy + 3x2 + 4y2) = 0

Combine like terms: -4xy + -3xy = -7xy
(-7xy + 3x2 + 4y2) = 0

Solving
-7xy + 3x2 + 4y2 = 0

Solving for variable 'x'.

Factor a trinomial.

Subproblem 1

Set the factor '(3x + -4y)' equal to zero and attempt to solve: Simplifying 3x + -4y = 0 Solving 3x + -4y = 0 Move all terms containing x to the left, all other terms to the right. Add '4y' to each side of the equation. 3x + -4y + 4y = 0 + 4y Combine like terms: -4y + 4y = 0 3x + 0 = 0 + 4y 3x = 0 + 4y Remove the zero: 3x = 4y Divide each side by '3'. x = 1.333333333y Simplifying x = 1.333333333y

Subproblem 2

Set the factor '(x + -1y)' equal to zero and attempt to solve: Simplifying x + -1y = 0 Solving x + -1y = 0 Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. x + -1y + y = 0 + y Combine like terms: -1y + y = 0 x + 0 = 0 + y x = 0 + y Remove the zero: x = y Simplifying x = y

Solution

x = {1.333333333y, y}
