Which steps are needed to solve this equation?
b+6= 21
Subtract 6 from both sides of the equation.
The answer is b= 15.
Check the solution by substituting 15 for b.
Subtract 6 from the left side and add 6 to the right side of the equation.
The answer is b= 27.
Check the solution by substituting 27 for b.
Add 6 to both sides of the equation.
The answer is b= 27.
Check the solution by substituting 27 for b.
Add 6 to the left side and subtract 6 from the right side of the equation.
The answer is b-15.
Check the solution by substituting 15 for b.

A- Subtract 6 from both sides of the equation.  The answer is b= 15.

For this equation, you need to do the opposite of the number in the same side of the variable. So, there is a +6. To get rid of the +6, you need to be -6.

6-6=0

21-6=15

You will be left with b on one side, and then 15 on the other side.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
