Can 2x +5xbe simplified? Explain [2]

Thank you in advance.

Hint: Do you know how to add?

because the variables (x) are the same (not squared or cubed or multiplyed by anything else, yes this can be simplified

x is common to everything in the equation.

7x =]

3x+2y=-8

3X+2Y=-8

To simplify your problem just add both sides of your equation by 8 so that your equation will equal zero.

So:
3X + 2Y = -8
3X + 2y + 8 = -8 + 8
3X + 2Y + 8 = 0

You cannot solve any further with what you have provided.
