Solve for B.
R = x(A + B)
a. B = (R - A)/x
b. B = (A - Rx)/x
c. B = (R - Ax)/x

Would you like me to explain how I did it?

- Bossvideogamer21

yes please.

For these algebra equations, I like to substitute the letters for simple numbers.
For example, for this equation R = x(A + B), I have made:
X = 2
A = 3
B = 4
So firstly, I worked out what R would be if I did that equation.
R = 2(3+4)
This equals to 14. This means R = 14
Then all I did is use each possible equation but substituted numbers into them until the answer I got was 4 (which is what I said B was)
For example:
a. B = (R - A)/x
Substituting numbers in, the equation would be: B = (14 - 3)/2
This equals 5.5, so this isn't the right equation.
b. B = (A - Rx)/x
Substituting numbers in, the equation would be B = (3 - (14 x 2)) / 2
This equals -12.5, so this isn't the right equation.
c. B = (R - Ax)/x
Substituting numbers in, the equation would be B = (14 - (3 x 2) / 2
This equals 4, so this is the right equation, as I said in the beginning B = 4
Does that make sense?

(14 - 3x2)) / 2
Sorry typo! Forgot the extra bracket
