Question

X-(0,25x+0,72*0,75x)=84​

Answer 1

Ответ:

$x-0,25-0,72*0,75x=84\\x-0,25-0,54x=84\\0,46x =84+0,25\\0,46x=84,25\\x=\frac{84,25}{0,46}$

Answer 2

To solve the equation, let's simplify and solve step by step:

X - (0.25x + 0.72 * 0.75x) = 84

First, we need to simplify the expression inside the parentheses:

0.72 * 0.75x = 0.54x (multiply 0.72 and 0.75)

Now we can substitute this simplified expression back into the equation:

X - (0.25x + 0.54x) = 84

Combine like terms within the parentheses:

X - (0.25x + 0.54x) = 84 X - 0.79x = 84

To isolate the variable X, we want to move the terms involving x to the other side of the equation. We can do this by adding 0.79x to both sides:

X - 0.79x + 0.79x = 84 + 0.79x X = 84 + 0.79x

Now we have the equation in terms of X.
