2 and 3 / 7 plus 2 and 4 / 7?
=5
Solve the equation: 2 and 1 / 7 plus 2x equals 3 and 1 / 5
It's not easy to type the symbols. I just type them in Chinese
2:7 plus 2x is 3:5
15/7+2x=16/5
75/35+2x=112/35
2x=112/35-75/35
2x=37/35
x=37/70

When Zhang Chi was doing the experiment of "changing the brightness of the lamp with a rheostat", she connected a small bulb in series with the sliding rheostat and the switch to the power supply, but after closing the switch, no matter how she moved the slide of the sliding rheostat, the light did not come on. In order to check the circuit fault, she took another voltmeter and connected the meter in parallel with the small bulb and the switch, the pointer of the meter did not move When it is connected in parallel with the sliding rheostat, the pointer of the meter is obviously deflected A.
