Question

(y+64)-38=49 3986+y=9704 6877-x=2984

Answer 1

Пошаговое объяснение:

(y+64)-38=49

у+64-38=49

у=49-26

у=23

3986+y=9704

у=9704-3986

у=5718

6877-x=2984

-х=2984-6877

-х=-3893

х=3893

Answer 2

To solve each of the equations, let's go through them one by one:

1. (y+64)-38=49

We'll simplify the equation step by step:

Start with (y+64)-38: y + 64 - 38 = 49

Combine like terms: y + 26 = 49

Next, isolate y by subtracting 26 from both sides: y + 26 - 26 = 49 - 26 y = 23

Therefore, the solution to the first equation is y = 23.

2. 3986+y=9704

To solve for y, we'll isolate it on one side of the equation:

Start with 3986 + y = 9704

Subtract 3986 from both sides: 3986 + y - 3986 = 9704 - 3986 y = 5718

So the solution to the second equation is y = 5718.

3. 6877 - x = 2984

To solve for x, we'll isolate it on one side of the equation:

Start with 6877 - x = 2984

Subtract 6877 from both sides: 6877 - x - 6877 = 2984 - 6877 -x = -3893

Multiply both sides by -1 to solve for x: -x * -1 = -3893 * -1 x = 3893

Therefore, the solution to the third equation is x = 3893.

To summarize the solutions:

1. y = 23
2. y = 5718
3. x = 3893
