Answer with explanation:
The equation is
5 x-2 =8
Adding 2 on both sides
→5 x-2+2=8+2
→5 x=10
Dividing both sides by,5, we get
→x=2
Using the concept of Logarithms
![1.\log_{a}b=\frac{\log b}{\log a}\\\\2.\log ab=\log a +\log b\\\\\rightarrow \log_{10}{5 x}=\log_{10} 10\\\\\rightarrow \log_{10}5+\log_{10} x=1\\\\0.698+\log_{10} x=1\\\\\log_{10} x=1-0.698\\\\ \frac{\log x}{\log 10}=0.302\\\\ \log x=(\log 10^{0.302})\\\\ \log x=\log 2.044\\\\x=2.004472](https://tex.z-dn.net/?f=1.%5Clog_%7Ba%7Db%3D%5Cfrac%7B%5Clog%20b%7D%7B%5Clog%20a%7D%5C%5C%5C%5C2.%5Clog%20ab%3D%5Clog%20a%20%2B%5Clog%20b%5C%5C%5C%5C%5Crightarrow%20%5Clog_%7B10%7D%7B5%20x%7D%3D%5Clog_%7B10%7D%2010%5C%5C%5C%5C%5Crightarrow%20%5Clog_%7B10%7D5%2B%5Clog_%7B10%7D%20x%3D1%5C%5C%5C%5C0.698%2B%5Clog_%7B10%7D%20x%3D1%5C%5C%5C%5C%5Clog_%7B10%7D%20x%3D1-0.698%5C%5C%5C%5C%20%5Cfrac%7B%5Clog%20x%7D%7B%5Clog%2010%7D%3D0.302%5C%5C%5C%5C%20%5Clog%20x%3D%28%5Clog%2010%5E%7B0.302%7D%29%5C%5C%5C%5C%20%5Clog%20x%3D%5Clog%202.044%5C%5C%5C%5Cx%3D2.004472)
Gives, x=2.005 (Approx)
Answer:
x=56
Step-by-step explanation:
16 x 7= x * 2
![x=\frac{16 x7}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B16%20x7%7D%7B2%7D)
x=56
Hope this helps :)
Answer:
(f - g)(x) = 3x - 7
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
= 4x - 3 - ( x + 4 )
= 4x - 3 - x - 4
= 3x -7
