Пошаговое объяснение:

$(171+(36-y):5):3=58\\\\171+(36-y):5=58*3\\\\171+(36-y):5=174\\\\(36-y):5=174-171\\\\(36-y):5=3\\\\36-y=3*5\\\\36-y=15\\\\y=36-15\\\\y=21$

Answer 2

To solve the equation, follow these steps:

Step 1: Simplify the expression inside the parentheses. Step 2: Simplify the expression inside the innermost set of parentheses (if any). Step 3: Perform the division. Step 4: Perform the addition or subtraction. Step 5: Check if the equation is true after evaluating both sides.

Let's start solving the equation step-by-step:

Step 1: Simplify the expression inside the parentheses. (171 + (36 - y) / 5) / 3 = 58

Step 2: Simplify the expression inside the innermost set of parentheses (if any). There are no innermost parentheses in this case.

Step 3: Perform the division. (171 + (36 - y) / 5) / 3 = 58 => (171 + (36 - y) / 5) = 58 * 3 => (171 + (36 - y) / 5) = 174

Step 4: Perform the addition or subtraction. (171 + (36 - y) / 5) = 174 => 171 + (36 - y) / 5 = 174 => (36 - y) / 5 = 174 - 171 => (36 - y) / 5 = 3

Step 5: Solve for y. To solve for y, multiply both sides by 5: 36 - y = 3 * 5 36 - y = 15

Now, isolate y by subtracting 36 from both sides: -y = 15 - 36 -y = -21

Finally, multiply both sides by -1 to solve for y: y = 21

The solution to the equation is y = 21.
