Final answer:
To solve the equation 3x = -4 for x, the correct step is to multiply each side by (1/3) to isolate x on one side of the equation.
Step-by-step explanation:
To solve the equation 3x = -4 for x, we need to isolate x on one side of the equation. We can do this by performing the same operation on both sides of the equation. In this case, we should multiply each side by (1/3), which is the reciprocal of the coefficient of x. This will cancel the 3 on the left side and leave us with x alone on that side.
Using the steps of problem-solving:
- Identify the unknown: x is the unknown.
- Identify the knowns: 3 (the coefficient of x) and -4 (the constant on the right side).
- Choose an equation and rearrange it to solve for x. Here, we divide both sides by 3 or equivalently multiply by (1/3).
So the correct step to solve the equation for x is multiply each side by (1/3).
