Question

Add 3x + 15y, - 7x + 5x – 6 and – 7y +2x – 11​

Answer 1

Given: The equations are$3x + 15y, - 7x + 5x-6, and -7y +2x- 11$.

We have to add the above equation.

• As we know that adding two or more numbers together is known as an addition.
• Addition as denoted by(+).

Properties of addition are as follows:

• Identity property of zero.
• Inverse property.
• Commutative property.
• Associative property.

We are solving in the following way:

We have,

$3x + 15y, - 7x + 5x-6, and -7y +2x- 11$

$=>3x+15y+(-7x+ 5x -6)+(- 7y +2x- 11)\\=>3x+15y-7x+5x-6-7y+2x-11\\=>3x-7x+5x+2x+15y-7y-6-11\\=>3x+8y-17$

Hence, the solution of the above equation is$3x+8y-17$.
