Question

(200-y):3=60 решите уравнение

Answer 1

200-y = 60*3
200-y = 180
y = 200-180
y = 20
(200-20):3=60
60=60

Answer 2

To solve the equation (200-y)/3 = 60, you need to isolate the variable y on one side of the equation. Here's how you can do it step-by-step:

1. Multiply both sides of the equation by 3 to eliminate the fraction: 3 * ((200-y)/3) = 3 * 60

2. Simplify the left side by canceling out the 3 in the denominator with the 3 in the numerator: 200 - y = 180

3. Now, let's isolate y by moving the constant term (-200) to the other side of the equation: -y = 180 - 200

4. Simplify the right side of the equation: -y = -20

5. To find y, divide both sides by -1 (since we want to isolate y): y = -20 / -1

6. The solution is: y = 20

Therefore, the value of y that satisfies the equation is y = 20.
