Question

7(x + 1) – 3(x - 2) = 5​

Answer 1

Ответ:

-2

Пошаговое объяснение:

7(x + 1) – 3(x - 2) = 5​

7x + 7 - 3X +6 = 5

7x + 7 - 3X + 6 -5 = 0

4x +8 = 0

4x = -8

x = - 8 : 4

x = - 2

Answer 2

To solve the equation 7(x + 1) - 3(x - 2) = 5, you'll need to distribute the constants outside the parentheses and then simplify the equation step by step. Here's how you can do it:

1. Distribute the constants on the left side of the equation:

7(x + 1) - 3(x - 2) = 5 7x + 7 - 3x + 6 = 5

2. Combine like terms on the left side of the equation:

(7x - 3x) + (7 + 6) = 5 4x + 13 = 5

3. Now, subtract 13 from both sides of the equation to isolate the variable (x):

4x + 13 - 13 = 5 - 13 4x = -8

4. Finally, divide both sides by 4 to solve for x:

4x/4 = -8/4 x = -2

So, the solution to the equation is x = -2.
