Question

B/4 +6= 9
what is b?
(Solve two-step equations)

Answer 1

The answer is b=12. I hope you have a nice day!

Answer 2

b = 12

Explanation:

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 6 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

`(b)/(4)` + 6 = 9

→ Minus 9 from both sides to isolate
`(b)/(4)`

`(b)/(4)` = 3

→ Multiply both sides by 4 to isolate b

b = 12

→ We can check if this solution is right by substituting b = 12 back into the original equation

`(b)/(4)` + 6 = 9

`(12)/(4)` + 6 = 9

3 + 6 = 9

9 = 9

→ So b = 12 is correct
