Answer 2

Given that 80 percent of x is 400

What is the definition of a linear equation?

A linear equation is an algebraic equation of the form $y=mx+b$, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included.

According to the question, we get

$x\times \frac{80}{100}=400\\\Rightarrow \frac{80x}{100}=400\\\Rightarrow \frac{8x}{10}=400\\\Rightarrow 8x=4000\\\Rightarrow x=\frac{4000}{8}\\\Rightarrow x=500$

therefore, the value of x is 500.
