To solve the equation 21 - 5x = 6, we first need to isolate the variable x by subtracting 21 from both sides:
21 - 21 - 5x = 6 - 21 -5x = -15
Next, divide by -5 to solve for x:
x = -15 / -5 x = 3
Therefore, the solution for x in the equation 21 - 5x = 6 is x = 3.
Given the equation у = 40.1x = 3 0.7 у = 0, it seems there may be a typo or formatting error in the expression. Please provide the equation in a clearer format if possible.
