Question

(n+4 21/34)-9 18/34=5 19/34 как решить это уравнение?

Answer 1

$\left(n+4\frac{21}{34}\right)-9\frac{18}{34}=5\frac{19}{34}\\n+4\frac{21}{34}=5\frac{19}{34}+9\frac{18}{34}\\n=14\frac{37}{34}-4\frac{21}{34}\\n=10\frac{16}{34}=10\frac8{17}$

Answer 2

Ответ:

Пошаговое объяснение:

(n+4 21/34)-9 18/34=5 19/34

n=-4 21/34+9 18/34+5 19/34

n=10 16/34=10 8/17

Answer 3

To solve the equation, we need to find the value of 'n'. Let's break down the steps to solve the given equation:

Step 1: Simplify the left-hand side (LHS) of the equation.

(n + 4 21/34) - (9 18/34) = 5 19/34

First, let's convert the mixed numbers into improper fractions: 4 21/34 = (4 * 34 + 21)/34 = 149/34 9 18/34 = (9 * 34 + 18)/34 = 336/34

Now, the equation becomes: (n + 149/34) - (336/34) = 5 19/34

Step 2: Combine like terms on the LHS.

To combine the fractions on the LHS, we need a common denominator, which is 34 in this case.

(n + 149/34) - (336/34) = (n + 149 - 336)/34

Now, the equation is: (n - 187)/34 = 5 19/34

Step 3: Convert the whole number on the right-hand side (RHS) into an improper fraction.

5 19/34 = (5 * 34 + 19)/34 = 199/34

Now, the equation is: (n - 187)/34 = 199/34

Step 4: Solve for 'n'.

To solve for 'n', we need to get rid of the denominator (34) on the LHS. We can do this by multiplying both sides of the equation by 34:

34 * (n - 187)/34 = 34 * (199/34)

The 34 on the left side cancels out, and we're left with:

n - 187 = 199

Step 5: Isolate 'n' on one side of the equation.

Add 187 to both sides to isolate 'n':

n - 187 + 187 = 199 + 187

n = 386

So, the solution to the equation is n = 386.
