Answer: 0 = 3
Step-by-step explanation: If y = 7 - 3x, we can plug that in for y in the equation 3x + y = 10 by writing it as 3x + 7 - 3x = 10.
- 7 - 7
--------------------------
3x - 3x = 3
0 = 3
4*2/5 = 22/5
16*1/2 = 33/2
22/5 ............. 1 min
33/2 ..............x min
x = 33/2 : 22/5 = 33/2 x 5/22 = 165/44 = 3,75 min
