Answer 3

Sure! Let's solve the equations step by step.

Equation 1: x^2 = 8

To solve this equation, we need to find the value of x that satisfies the equation.

Taking the square root on both sides of the equation, we get:

√(x^2) = √8 x = ±√8

So, the solutions to this equation are x = √8 and x = -√8.

Equation 2: x/3 = 5

To solve this equation, we need to isolate x.

Multiplying both sides of the equation by 3, we get:

3 * (x/3) = 3 * 5 x = 15

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

Equation 3: 14/x = 7

To solve this equation, we need to isolate x.

Multiplying both sides of the equation by x, we get:

x * (14/x) = x * 7 14 = 7x

Dividing both sides of the equation by 7, we get:

14/7 = x 2 = x

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

In summary, the solutions to the given equations are: - Equation 1: x = √8 and x = -√8 - Equation 2: x = 15 - Equation 3: x = 2
