The sum of number a and number B is 210, and 13 of number a is equal to 14 of number B?
A: B = 14:13 = 3:4; a: 210 × 33 + 4 = 210 × 37 = 90; B: 210-90 = 120
The sum of the numbers a and B plus the number a is 210. If the number B is added, it is 180. The number a is 210______ The number B is______ ．
Let B be x, then a is x + 30. According to the sum of a and B and the number of a equals 210, we can get x + 30 + X + 30 = 210, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 3x = 210-6
The sum of number a and number B is 210, and 13 of number a is equal to 14 of number B?

The sum of the numbers a and B plus the number a is 210. If the number B is added, it is 180. The number a is 210______ The number B is______ ．
According to the meaning of the title: (a + b) + a = 210, (a + b) + B = 180, we can get: A is 30 more than B, let B be x, then a is x + 30, according to the sum of a and B plus the number of a equals 210, we can get: x + 30 + X + X + 30 = 210, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 3x = 210-60, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 3x = 150, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; &X = 50, number A: 50 + 30 = 80, answer: number a is 80, number B is 50
