Answer 1

i will award a medal to anyone who helps

Answer 2

We can re-arrange the 2nd equation.

y + 2x = 5

Subtract 2x to both sides:

y = -2x + 5

Now we can plug in '-2x + 5' for 'y' in the 2nd equation:

x = y + 16

x = -2x + 5 + 16

Add 5 + 16 @Blackula123

Answer 3

21

Answer 4

Yes, now we have:

x = -2x + 21

Now add 2x to both sides, what's 2x + x?

Answer 5

3x

Answer 6

Yes, so we have:

3x = 21

Now divide 3 to both sides, what's 21 / 3?
