you have to get by on its own. Any idea how? where to start?

2. anonymous

nop

3. anonymous

i'd start by subtracting d and putting it on the other side

4. anonymous

then proceed to divide the whole thing by a

5. anonymous

that should get you b on its own

you want to isolate B $$C=AB+D$$ first step would be to get rid of D it is +D so the opposite is -D $$C-D=AB$$ Next divide A since AB is A*B and you need the opposite $$\dfrac{C-D}{A}=B$$

subtract d from both sides, then divide by a, it should look like this $\frac{ C-D }{ A }=B$ Hope this helped

C = AB + D 1) Subtract D on both sides to leave AB alone because the goal is to get B: C-D=AB 2) Divide A since it is being multiplied to B on both sides to cancel A on the right where the AB is. (C-D)/A = B B= C-D/A
