Answer:

5x^2 + 20x = 5x(x + 4)

Step-by-step explanation:

To do this, we start by writing the common factors

The common actor that we can see which is in the form of the gcf of both is 5x

2x + y = 7<br> -2x - y = 6<br> Solve systems of equations by substitution
ehidna [41]

Answer:

No solution.

Step-by-step explanation:

2x + y = 7

-2x - y = 6

From the first equation:

y = 7 - 2x

Plug this into the second equation:

-2x - (7 - 2x) = 6

-2x  + 2x = 6 + 7

0 = 13

this doesn't make sense so theer is:

No solution.
