Solve the following equation for x to find the total number of people who became members of a social networking site for a certa

Aleksandr [31]

Answer:

x = 360

Step-by-step explanation:

Reorder the terms:

x = 72 + 0.8x

Solving

x = 72 + 0.8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-0.8x' to each side of the equation.

x + -0.8x = 72 + 0.8x + -0.8x

Combine like terms: x + -0.8x = 0.2x

0.2x = 72 + 0.8x + -0.8x

Combine like terms: 0.8x + -0.8x = 0.0

0.2x = 72 + 0.0

0.2x = 72

Divide each side by '0.2'.

x = 360

Simplifying

x = 360
