Final answer:
To solve the equation -7-3x=-17, add 7 to both sides and then divide by -3 to find the value of x. The answer is approximately 3.33. Plot this value on the number line.
Step-by-step explanation:
To solve the equation -7-3x=-17, you need to isolate the variable x by performing inverse operations.
- Start by adding 7 to both sides of the equation to get -3x = -10.
- Then, divide both sides of the equation by -3 to solve for x. This gives x = -10/-3, which simplifies to x = 10/3 or approximately 3.33.
To plot the answer on the number line, locate the point 10/3 (or approximately 3.33) on the number line and mark it with a dot.
