Question

Finding the Solution to a Two-Step Equation Solve the two-step equation. 5.1 = –3x – 4.2 1. Add 4.2 to both sides. 2. Divide both sides by -3. The solution is x = .

Answer 1

-3.1

Explanation:

5.1 = –3x – 4.2

1. Add 4.2 to both sides.

9.3 = -3x

2. Divide both sides by -3.

9.3/-3

The solution is x = -3.1

Answer 2

x= -3.1

Explanation:

5.1 = –3x – 4.2

Add 4.2 to each side

5.1 +4.2= –3x – 4.2+4.2

9.3 = -3x

Divide each side by -3

9.3 / -3 = -3x/-3

-3.1 =x
