Question

5 ( x -1 ) + 7 = 3 ( x + 1 ) + 1

Answer 1

Ответ:

5x - 5 + 7 = 3x + 3 + 1

5x - 3x=5 - 7 + 4

2x = 2

x = 1

Answer 2

Ответ:

5х-5+7=3х+3+1

5×-3×=4+5-7

2×=2

×=1

Answer 3

To solve the equation 5(x - 1) + 7 = 3(x + 1) + 1, you'll need to simplify and isolate the variable x. Here's how you can do it step by step:

1. Distribute the constants outside the parentheses:

   5(x) - 5(1) + 7 = 3(x) + 3(1) + 1

2. Now, simplify the equation by multiplying the constants with the terms inside the parentheses:

   5x - 5 + 7 = 3x + 3 + 1

3. Combine like terms on both sides of the equation:

   5x + 2 = 3x + 4

4. To isolate the variable x on one side, you can subtract 3x from both sides of the equation:

   5x - 3x + 2 = 4

5. Simplify further:

   2x + 2 = 4

6. Next, subtract 2 from both sides to get the x term by itself:

   2x + 2 - 2 = 4 - 2

   2x = 2

7. Finally, divide both sides by 2 to solve for x:

   2x / 2 = 2 / 2

   x = 1

So, the solution to the equation is x = 1.
