Как решить уравнение? 8(y-7)-3(2y=9)=15 ответ в учебнике 49

Answer 1

8(y-7)-3(2y+9)=15
8у-56-6у-27=15
2у=98
у=49

Answer 2

Solving the Equation 8(y-7)-3(2y=9)=15

To solve the equation 8(y-7)-3(2y=9)=15, we can follow these steps:

1. Distribute the terms inside the parentheses: - 8(y-7) becomes 8y - 56 - 3(2y-9) becomes 6y - 27

2. Combine like terms: - 8y - 56 - 6y - 27 = 15 - (8y - 6y) + (-56 - 27) = 15 - 2y - 83 = 15

3. Isolate the variable y: - Add 83 to both sides: 2y = 15 + 83 - 2y = 98 - Divide by 2: y = 49

So, the solution to the equation 8(y-7)-3(2y=9)=15 is y = 49.
