Answer: The different possible solutions are 42, 21, 31 and 80.
Explanation:
The given expression is,
![7+3\cdot 4+2](https://tex.z-dn.net/?f=7%2B3%5Ccdot%204%2B2)
Case 1.
![(7+3)\cdot 4+2=10\cdot 4+2](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%204%2B2%3D10%5Ccdot%204%2B2)
![(7+3)\cdot 4+2=40+2](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%204%2B2%3D40%2B2)
![(7+3)\cdot 4+2=42](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%204%2B2%3D42)
Case 2.
![7+(3\cdot 4)+2=7+12+2](https://tex.z-dn.net/?f=7%2B%283%5Ccdot%204%29%2B2%3D7%2B12%2B2)
![7+(3\cdot 4)+2=21](https://tex.z-dn.net/?f=7%2B%283%5Ccdot%204%29%2B2%3D21)
Case 3.
![7+3\cdot (4+2)=7+3\cdot 8](https://tex.z-dn.net/?f=7%2B3%5Ccdot%20%284%2B2%29%3D7%2B3%5Ccdot%208)
![7+3\cdot (4+2)=7+24](https://tex.z-dn.net/?f=7%2B3%5Ccdot%20%284%2B2%29%3D7%2B24)
![7+3\cdot (4+2)=31](https://tex.z-dn.net/?f=7%2B3%5Ccdot%20%284%2B2%29%3D31)
Case 4.
![(7+3)\cdot (4+2)=10\cdot 8](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%20%284%2B2%29%3D10%5Ccdot%208)
![(7+3)\cdot (4+2)=80](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%20%284%2B2%29%3D80)
Answer:
x=-24
Step-by-step explanation:
Multiply both sides by 4 to get x=-24
Answer:
x=2
Step-by-step explanation:
first divide by 3 left and right, then you get:
x+1 = 3
then subtract 1 left and right, then you get:
x=2
so, solutions appear by simplifying
I think the answer is B) 35
Ok, so your answer would be 89.75
