Question

Solve C = AB + D for B

A. C + D/A = B
B. AC - D =B
C. C/A - D = B
D.C-D/A = B

Answer 1

D

Explanation:

To solve for B, we must get B by itself. Perform the inverse operation of the equation. Remember to perform everything to both sides.

C= AB+D

D is being added to AB. The opposite of addition is subtraction. Subtract D from both sides

C-D= AB+D-D

C-D=AB

B is being multiplied by A. The opposite of multiplication is division. Divide both sides by A.

C-D/A=AB/A

C-D/A=B

Therefore, the correct answer is D: C-D/A=B

Answer 2

(C-D)/A = B

Explanation:

C = AB + D

Subtract D from each side

C-D = AB

Divide each side by A

(C-D)/A = AB/A

(C-D)/A = B
