Question

Steve · Accepted Answer

a = 7b a-294 = b+294 7b-294 = b+294 6b = 588 b = 98 so, a=7b=686 check: 686-294 = 98+294 = 392

Martin · Answer

Steve got 588 by cancelling out 1 b I'll break it down, try to follow..... Example: 7b-294 = b+294 7b = b+294+294 7b = b+588 ------------------- 6b = +588 588/6 = 98 1b = 98
