Question

If 2x + 5y = 21 and x + y = 3, then what is the value of x?

Answer 1

Respuesta:

Explicación paso a paso:

I believe x=3.

If you plug in 0 for X in x+y=3, you get that y=3.

When you plug it in (2x+5(3)=21) you get 2x+15=21.

When you subtract 15 from 21, you're left with 2x=6. Divide both sides by 2, and x=3.

I hope I was able to help. Best of luck.
