Question

10 – 2 ( у + 5 ) = у – 3

Answer 1

Ответ:

y  = -3

Пошаговое объяснение:

10 - 2 ( y + 5 )  = y - 3

10 - 2y - 10 = y - 3

2y = y - 3

2y - y = - 3

y = -3

Вот решение... лучше разберись с этой темой, а то потом будет сложно.

Answer 2

To solve the equation $10 - 2 (y + 5) = y - 3$, we need to follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) to simplify and solve for the variable $y$. Here's how you can solve it step by step:

1. Distribute the -2 on the left side of the equation: $10 - 2y - 2 \cdot 5 = y - 3$

2. Simplify the terms on the left side: $10 - 10 - 2y = y - 3$

3. Combine like terms on both sides of the equation: $-2y = y - 3$

4. Add $2y$ to both sides of the equation to isolate the variable $y$ on one side: $-2y + 2y = y - 3 + 2y$ $0 = 3y - 3$

5. Add 3 to both sides of the equation to solve for $y$: $0 + 3 = 3y - 3 + 3$ $3 = 3y$

6. Divide both sides by 3 to find the value of $y$: $y = \frac{3}{3}$ $y = 1$

So, the solution to the equation is $y = 1$.
