If a =bc+us, which equation is solved for s?

(A-bc)/u

You first subtract both sides by bc to get the us term alone, then divide everything by u to get s term alone.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
