Answer 2

Відповідь:120

Покрокове пояснення:

63+9х-5х=5х-57

9х-5х-5х=-57+(-63)

-1х=-120

Х=120

Answer 3

Let's solve the given equation step by step:

9(7 + x) - 5x = 5x - 57

1. First, distribute the 9 on the left side of the equation:

63 + 9x - 5x = 5x - 57

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

(9x - 5x) + 63 = 5x - 57

3. Simplify the expression on the left side:

4x + 63 = 5x - 57

4. Move all the terms involving 'x' to one side of the equation. Let's move the 5x term to the left side by subtracting 5x from both sides:

4x + 63 - 5x = 5x - 57 - 5x

4. Simplify further:

4x - 5x + 63 = -57

5. Combine like terms again:

-1x + 63 = -57

6. Now, isolate the 'x' term by moving the constant term (63) to the other side of the equation. To do this, subtract 63 from both sides:

-1x + 63 - 63 = -57 - 63

7. Simplify:

-1x = -120

8. Finally, to solve for 'x', divide both sides by -1:

x = -120 / -1

x = 120

So, the value of 'x' that satisfies the equation is 120.
