Question

Use the drop-down menus to choose steps in order to correctly solve 1+2b−13=12−4b−2b for b.

Answer 1

Answer:

2b = 24 - 6b

8b = 24

b = 3

Answer 2

Answer:

$b=3$

Step-by-step explanation:

Given equation:

$1+2b-13=12-4b-2b$

Solving for $b$

Combining like terms on both sides.

$2b+1−13=12-4b-2b$

$2b-12=12-6b$

Adding $6b$ both sides to get $b$ terms on one side.

$2b-12+6b=12-6b+6b$

$8b-12=12$

Adding 12 both sides to isolate $b$ on one side.

$8b-12+12=12+12$

$8b=24$

Dividing both sides by 8.

$\frac{8b}{8}=\frac{24}{8}$

∴ $b=3$  (Answer)
