SAT数学怎么写
Bob has a pile of poker chips that he wants to arrange in even stacks.If he stacks them in piles of 10,he has 4 chips left over.If he stacks them in piles of 8,he has 2 chips left over.If Bob finally decides to stack the chips in only 2 stacks,how many chips could be in each stack?
后面没选项

10x+4=8y+2,x和y都是偶数.我觉得你只能看那5个选项,然后一项项试.二元一次方程不能解
SAT不都是选择题么?怎么可能没选项?
