Question

3) (x + 76): 7 = 15;​

Answer 1

Ответ:

(x+76):7=15

(x+76)=15•7

x+76=105

x=105-76

x=29

Answer 2

To solve the equation (x + 76) ÷ 7 = 15, we can follow these steps:

1. Remove the parentheses by distributing the division operation: x/7 + 76/7 = 15

2. Simplify the equation by dividing 76 by 7: x/7 + 10.857 = 15

3. Subtract 10.857 from both sides of the equation to isolate x/7: x/7 = 15 - 10.857

4. Subtract 10.857 from 15 to get the result: x/7 = 4.143

5. Multiply both sides of the equation by 7 to solve for x: 7 * (x/7) = 7 * 4.143 x = 28.999

So the solution to the equation is x = 28.999.
