Question

Free points, solve 4b+5b=8b-1+3b+15?​

Answer 1

Answer: Hi!

First, we should combine like terms:

4b + 5b = 8b − 1 +3b + 15 =

9b = 11b + 14

Now, we should subtract 11b from both sides.

-2b = 14

Now, we should divide both sides by -2.

b = -7

Hope this helps!

Answer 2

Answer:

$\Huge \boxed{b=-7}$

Step-by-step explanation:

$4b+5b=8b-1+3b+15$

Combining like terms.

$9b=11b+14$

Subtracting 9b and 14 from both sides.

$-14=11b-9b$

$-14=2b$

Dividing both sides by 2.

$-7=b$
