The area of the first experimental field is 100 square meters more than three times that of the second one. The two experimental fields have a total area of 2900 square meters. What are the area of the two experimental fields

The area of the first experimental field is 100 square meters more than three times that of the second one. The two experimental fields have a total area of 2900 square meters. What are the area of the two experimental fields

Suppose the area of the second test field is x square meters, then the area of the first test field is 3x + 100 square meters. According to the meaning of the title, we can get the equation: x + 3x + 100 = 2900 & nbsp; 4x + 100 = 2900 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 4x = 2800 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 700700 × 3 + 100 = 2200 square meters a: the area of the first plot is 2200 square meters, and the area of the second plot is 700 square meters

The science and technology group of Jingshan middle school has two wheat experimental fields. The second one is 16 square meters less than the first one. The area of the first one is three times that of the second one

The second block = 16 ÷ (3-1) = 8 square meters
Total = 8 × 3 + 8 = 32 square meters

The area of the first experimental field is 100 square meters more than three times that of the second one. The two experimental fields have a total area of 2900 square meters. What are the area of the two experimental fields

Suppose the area of the second test field is x square meters, then the area of the first test field is 3x + 100 square meters. According to the meaning of the title, we can get the equation: x + 3x + 100 = 2900 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 4X = 2800 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 70070
