Question

Add (-4x+5y)+(-2x+7y)​

Answer 1

Answer:

Step-by-step explanation:

Simplifying

(4X + -5Y)(2X + 7Y) = 0

Multiply (4X + -5Y) * (2X + 7Y)

(4X * (2X + 7Y) + -5Y * (2X + 7Y)) = 0

((2X * 4X + 7Y * 4X) + -5Y * (2X + 7Y)) = 0

Reorder the terms:

((28XY + 8X2) + -5Y * (2X + 7Y)) = 0

((28XY + 8X2) + -5Y * (2X + 7Y)) = 0

(28XY + 8X2 + (2X * -5Y + 7Y * -5Y)) = 0

(28XY + 8X2 + (-10XY + -35Y2)) = 0

Reorder the terms:

(28XY + -10XY + 8X2 + -35Y2) = 0

Combine like terms: 28XY + -10XY = 18XY

(18XY + 8X2 + -35Y2) = 0

Solving

18XY + 8X2 + -35Y2 = 0

Solving for variable 'X'.

Factor a trinomial.

(4X + -5Y)(2X + 7Y) = 0

Subproblem 1

Set the factor '(4X + -5Y)' equal to zero and attempt to solve:

Simplifying

4X + -5Y = 0

Solving

4X + -5Y = 0

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

Add '5Y' to each side of the equation.

4X + -5Y + 5Y = 0 + 5Y

Combine like terms: -5Y + 5Y = 0

4X + 0 = 0 + 5Y

4X = 0 + 5Y

Remove the zero:

4X = 5Y

Divide each side by '4'.

X = 1.25Y

Simplifying

X = 1.25Y

Subproblem 2

Set the factor '(2X + 7Y)' equal to zero and attempt to solve:

Simplifying

2X + 7Y = 0

Solving

2X + 7Y = 0

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

Add '-7Y' to each side of the equation.

2X + 7Y + -7Y = 0 + -7Y

Combine like terms: 7Y + -7Y = 0

2X + 0 = 0 + -7Y

2X = 0 + -7Y

Remove the zero:

2X = -7Y

Divide each side by '2'.

X = -3.5Y

Simplifying

X = -3.5Y

Solution

X = {1.25Y, -3.5Y}

Answer 2

Answer:

Hey mate, Good afternoon ♡

#Here's ur answer...☆☆☆

Step-by-step explanation:

$( - 4x + 5y) + ( - 2x + 7y) \\ = - 4x + 5y - 2x + 7y \\ = - 4x - 2x + 5y + 7y \\ = - 6x + 12y \\ = - 6(x - 2y) \: answer...$

Hope this helps you....
