First, we use distributive property:

-9x - 45 + 81 = 9x - 9

Then, combine like terms: -45 + 81

-9x + 36 = 9x - 9

Add 9 to both sides.

-9x + 45 = 9x

Add 9x to both sides

45 = 18x

Divide both sides by 18

2.5 = x

What is the solution to the liner equation <br><br> -12+3b-1=-5-b

Natalija [7]

Answer:

b=2

Step-by-step explanation:

-12+3b-1=-5-b

Combine like terms

-13 +3b = -5-b

Add b to each side

-13+3b+b = -5-b+b

-13+4b = -5

Add 13 to each side

-13+13 +4b = -5+13

4b = 8

Divide by 4

4b/4 = 8/4

b = 2
