Final answer:
Solving the equation 3x/-4 = 20 involves multiplying both sides by -4 and then dividing by 3 to isolate x, resulting in x = -80/3. The variable a is not relevant to this equation.
Step-by-step explanation:
To solve the equation 3x/-4 = 20 for x, follow these steps:
- Multiply both sides of the equation by -4 to get rid of the denominator on the left side, which gives us 3x = -80.
- Next, divide both sides by 3 to isolate x, resulting in x = -80/3.
Therefore, the value of x in terms of a is not relevant here because the variable a does not appear in the original equation.
