Answer:
x = 48
Step-by-step explanation:
3x + 9 = 153
subtract 9 from both sides -9 -9
3x = 144
divide both sides by 3 3x/3 = 144/3
2x + (x + 9) = 153
2(48) + (48 + 9) = 153
96 + 57 = 153
153 = 153
I believe the third option is correct. However, you have the equations wrong. The first one should be y≥2x+1
1 - 5
2 - 7
3 - 9
4-11
5-13
6-15
7- 17
8 - 19
9 - 21
10 - 23
To find the total weight of error subtract the measured weight from the actual weight
3900kg (actual weight) - 3867kg (measured weight) = 33 kg erorr
