x + xy + y + yx + x

= 2x + y + 2xy

4 - 2x + x² + 2x + 4

= x² + 8

10x - 2y

We must identify the like terms and combine them:

4x + 5y + 6x - 7y

4x + 6x = 10x

5y - 7y = -2y

Therefore, the simplified ex...

When it comes to equations that have more than one symbol, you must always follow BODMAS: Brackets, Order, Division, Multiplication, Addition, Subtraction.

The equation we have is 2 + 8 x 3, using ...
