Question

n/3+1=4-n solve it solve it fast


​

Answer 1

Answer:

$\green{\ { \boxed{ \frac{n}{3} + 1 = 4 - n }}}$

$\frac{n + 3}{3} = 4 - n \\ \\ n + 3 = 12 - 3n \\ \\ 4n = 9 \\ \\ \pink{n = \frac{9}{2} }$

Answer 2

Step-by-step explanation:

n:3 + 1 = 4-n

n:3 +1 -4+n = O (whole eqn multiplied with 3 )

3x n:3 + 3x 1 + 3(-4 +n) =O X3

n +3 -12 +3n = O

4n -9 =O

4n =9

n =9:4
