Question

Step 2: he should have added 3 to, rather than subtracting 3 from, both sides. What is the correct step-by-step explanation for solving the equation 6b - 3 = -21?

Answer 1

To solve the equation 6b - 3 = -21, add 3 to both sides, simplify, and divide by 6 to solve for b.

Step-by-step explanation:

To solve the equation 6b - 3 = -21, you need to isolate the variable b. Here are the correct steps:

1. Add 3 to both sides of the equation: 6b - 3 + 3 = -21 + 3
2. Simplify: 6b = -18
3. Divide both sides by 6 to solve for b: 6b ÷ 6 = -18 ÷ 6
4. Simplify: b = -3

Therefore, the solution to the equation 6b - 3 = -21 is b = -3.
