Question

solve for x.
\\( -20 = -\frac{x}{4} \\)
simplify your answer as much as possible.
\\( x = \\)
(there is a box for input and some buttons for fraction and other operations, and a reset and close button)

Explanation:

Step1: Multiply both sides by -4

To solve for \( x \), we can multiply both sides of the equation \( -20 = -\frac{x}{4} \) by -4 to isolate \( x \).
Multiplying both sides by -4 gives: \( (-20) \times (-4) = -\frac{x}{4} \times (-4) \)

Step2: Simplify both sides

Simplifying the left side: \( (-20) \times (-4) = 80 \)
Simplifying the right side: \( -\frac{x}{4} \times (-4) = x \) (because the -4 in the numerator and denominator cancels out)
So we get \( x = 80 \)

Answer:

\( x = 80 \)
