Question

The product 7X+8Y+4X-5Y is ​

Answer 1

Step-by-step explanation:

Simplifying

7x + 8y + -4x + 5y = 0

Reorder the terms:

7x + -4x + 8y + 5y = 0

Combine like terms: 7x + -4x = 3x

3x + 8y + 5y = 0

Combine like terms: 8y + 5y = 13y

3x + 13y = 0

Solving

3x + 13y = 0

Solving for variable 'x'.

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

Add '-13y' to each side of the equation.

3x + 13y + -13y = 0 + -13y

Combine like terms: 13y + -13y = 0

3x + 0 = 0 + -13y

3x = 0 + -13y

Remove the zero:

3x = -13y

Divide each side by '3'.

x = -4.333333333y

Simplifying

x = -4.333333333y
