Answer: the solution is $n=\frac{51}{11} \\\\\\n=4\frac{7}{11} \\\\n=4.63$

i gave you the decimal and improper fraction

Step-by-step explanation:

Mutiply both sides by 28

7(n-3)+4(n-5)=10

distribute the 7

7n-21+4(n-5)=10

distribute the 4

7n-21+4n-20=10

combine like terms

11n-21-20=10

11n-41=10

11n-51

So listen to this logic
lets say you have 3 numbers, m,a,x where they are all positivie
m>a>x
therefor
m^2>a>2>x^2
if m and a and x are square roots, therefor we can reverse the square root
confusing sorry

square 5 and 6
5^2=25
6^2=36

the number betwe 25 and 36

that would be 32

answer is √32

goes like this
5^2<32<6^2
sqrt both sides
5<√32<6

answer is √32
