Question

( y + 1 8 ) - 1 5 = 60​

Answer 1

у + 18 - 15 = 60

у + 18 = 60 + 15

у + 18 = 75

у = 75 - 18

у = 57

Answer 2

To solve the equation $(y + \frac{18}{15}) = 60$, you can follow these steps:

Step 1: Simplify the equation.

First, simplify the fraction on the left side of the equation:

$y + \frac{18}{15} = 60$

Step 2: Further simplify the fraction.

Reduce the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3:

$y + \frac{6}{5} = 60$

Step 3: Isolate the variable $y$.

To isolate the variable $y$, subtract $\frac{6}{5}$ from both sides of the equation:

$y + \frac{6}{5} - \frac{6}{5} = 60 - \frac{6}{5}$

This simplifies to:

$y = 60 - \frac{6}{5}$

Step 4: Perform the subtraction on the right side.

To subtract a fraction from a whole number, you'll need to find a common denominator. In this case, the common denominator is 5. Rewrite 60 as a fraction with a denominator of 5:

$y = \frac{300}{5} - \frac{6}{5}$

Now subtract the fractions:

$y = \frac{300 - 6}{5}$

$y = \frac{294}{5}$

Step 5: Simplify the fraction, if necessary.

The fraction $\frac{294}{5}$ can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3:

$y = \frac{294 ÷ 3}{5 ÷ 3}$

$y = \frac{98}{5}$

So, the solution to the equation $(y + \frac{18}{15}) = 60$ is $y = \frac{98}{5}$ or $y = 19.6$.
