Answer: Infinite solutions
Step-by-step explanation: 3x -7 = 3(x-3)+2
3x + -7 = (3)(x) + (3)(-3) + 2
3x + -7 = 3x + -9 + 2
3x - 7 = (3x) + (-7)
3x -7 - 3x = 3x - 7 - 3x
-7 + 7 = -7 + 7
0 = 0
Well first 9450/5=1890 then 1890/6= 315 watt hours per day
Dividing (3x^2-2x) by x gives out 3x-2
The 3 would be the y, so it would be 4x-3y
