Question

6x (2y-y) + 7 (2х - у)​

Answer 1

Answer:

The final answer is 6xy+14x-7y

Step-by-step explanation:

First, you multiply the number outside the brackets with the numbers inside. So you multiply 6x with 2y which will result in 12xy as the variables will multiply too. Next, you multiply 6x with the other variable in the brackets, -y. It will result in -6xy.

Onto the next part of the expression, 7 multiplied by 2x. The answer of this will be 14x. 7 multiplied by -y will be -7y.

Now, this has become: 12xy -6xy +14x -7y.

This can be simplified by adding/subtracting, which depends on the sign of the number, the numbers with the same variables.

6xy+14x-7y.

I hope this is what you wanted.
