Hey there! First you start with parenthesis! So distribute the 2 to 3x. There you get 6x. Now distribute to the 3. You get 6. Now you move the 2x over to the right side. Getting 30=4x+6.. Now move the 6 over to the 30. You get 24=4x..Now you divide, getting the answer 6! Hope this helps...

N = x + y - n = 5<br> and part two<br> x = u + v = o<br><br> whats the answer?
Colt1911 [192]
Just substitute the value of x from second equation into first equation:
N = x + y - n = 5
N = u + v  + y - n = 5
N = 0 + y - n = 5

In short, N would be equal to y - n which is still equal to 5

Hope this helps!
