1.When 8 is added to the product of 6 and a number, the result is 62. Find the number. let x be the number 8+6x=62 6x=54 x=9 2.When 23 is subtracted from the product of 5 and a number, the result is 32. let x be the number 5x-23=32 5x=55 x=11 3.When 3 is multipiled by the sum of 7 and a number, the result is 48. Find the number. let x be the number 3(7+x)=48 7+x=16 x=9 4. When 90 minus the product of 6 and a number, the result is 36. Find the number. let x be the number 90-6x=36 54=6x x=9 2007-10-13 14:38:27 補充： 上面果位朋友計錯數
