if 4 less than 3 times a certain number is 2 more than the number,what is the number

if 4 less than 3 times a certain number is 2 more than the number,what is the number
if 4 less than 3 times a certain number is 2 more than the number,what is the number

if 4 less than 3 times a certain number is 2 more than the number,what is the number
答案是:3
汉语:一个数字的三倍减去4等于这个数字加上2,那么这个数字是几?
计算:
3x - 4 = 2 + x
---> 2x = 6
---> x = 3

直译:如果4小于一个数的3倍,但(结果)又比那个数多2,问这个数是多少?
解题:设那个数为X,4既然比它的3倍小,即3X-4还有余,题目又说结果比该数还多2,所以可列出方程:
3X-4=X+2
移项后得:3X-X=2+4
所以 2X=6
故 X=3

句子中的certain number 我们用A来代替的话,公式应该是:
4 < 3A = 2 > A
A应该是>=1.34 但是 < 2
也就是 2 < A > (4/3)
