Answer:
![x=2.8](https://tex.z-dn.net/?f=x%3D2.8)
Step-by-step explanation:
![7x+3=10x-5.4](https://tex.z-dn.net/?f=7x%2B3%3D10x-5.4)
Subtract 3 from both sides:
![7x+3-3=10x-5.4-3](https://tex.z-dn.net/?f=7x%2B3-3%3D10x-5.4-3)
![7x=10x-8.4](https://tex.z-dn.net/?f=7x%3D10x-8.4)
Subtract 10x from both sides:
![7x-10x=10x-8.4-10x](https://tex.z-dn.net/?f=7x-10x%3D10x-8.4-10x)
![-3x=-8.4](https://tex.z-dn.net/?f=-3x%3D-8.4)
Divide both sides by -3:
![\frac{-3x}{-3}=\frac{-8.4}{-3}](https://tex.z-dn.net/?f=%5Cfrac%7B-3x%7D%7B-3%7D%3D%5Cfrac%7B-8.4%7D%7B-3%7D)
![x=2.8](https://tex.z-dn.net/?f=x%3D2.8)
Answer:
![32x^{4}- 28x^{3}y+12 x^{2}y^{2}](https://tex.z-dn.net/?f=32x%5E%7B4%7D-%2028x%5E%7B3%7Dy%2B12%20x%5E%7B2%7Dy%5E%7B2%7D)
