Which steps are needed to solve this equation b+6=21

b=15

Step-by-step explanation:

Okay so if we are solving for B the first thing you need to do is subtract 6 on both sides because we are trying to get alone

b+6=21

 -6     -6

21-6=15

b=15

b = 15 is the solution of equation.

Step-by-step explanation:

We have given the following equation:

b+6 = 21

We have to solve the above equation.

First, adding -6 to both sides of equation we get,

b+6-6 = 21 - 6

b= 21 - 6

b = 15

b = 15 is the solution of equation.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
