Question

Add 8y - 4x + 3 to 3x - 5y +6​

Answer 1

Given: The equation is$8y - 4x + 3 \ and\ 3x - 5y +6$.

We have to add the above equations.

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

Following are the properties of addition:

1. Identity property of zero.
2. Inverse property.
3. Commutative property.
4. Associative property.

We are solving in the following way:

We have,

The equation is$8y - 4x + 3 \ and\ 3x - 5y +6$.

Solving like terms:

$=>3x - 5y +6+ 8y - 4x + 3\\=>3x-4x-5y+8y+6+3\\=>-1x+3y+9$

Hence, the solution of the above equation is$-1x+3y+9$.

Answer 2

The addition of the given equations is 3y - 1x + 9.

Given:

Two Equations,

                         8y - 4x + 3

                         3x - 5y + 6

To Find:

Sum of given equations.

Solution:

For Finding the sum,

The quantity with the same variable coefficient will be calculated to get the sum.

So,

                                   $~~~~~8y-4x+3\\\underline{+-5y+3x+6~~~}\\\underline{~~~~~~3y-1x+9~~~}$

Here the same variable coefficients are added.

For the coefficient of y,

                      8 + ( -5 ) = 3

For the coefficient of x,

                      -4 + 3 = -1

For constant quantity,

                      3 + 6 = 9

Sum calculated to be,

                      3y - 1x + 9
