Question

B) (x + 90) - 30 = 75.​

Answer 1

Пошаговое объяснение:

х+90=75+30

х=105-90

х=15

Answer 2

Відповідь:

(x + 90) - 30 = 75

х + 90 - 30 = 75

х + 60 = 75

х = 75-60

х = 15

(15 + 90) - 30 = 75

105 - 30 = 75

75 = 75

Answer 3

To solve the equation (x + 90) - 30 = 75, you'll want to isolate the variable x. Here's how you can do it step by step:

1. Start with the given equation: (x + 90) - 30 = 75

2. First, simplify within the parentheses by adding 90 and subtracting 30: x + 90 - 30 = 75

3. Now, simplify further: x + 60 = 75

4. To isolate x, you can subtract 60 from both sides of the equation to get: x + 60 - 60 = 75 - 60

5. Simplify: x = 15

So, the solution to the equation is x = 15.
