(3x - 2) / (8) = (x/4) - 1

Multiply each side by 8 :

3x - 2 = 2x - 8

Add 2 to each side:

3x = 2x - 6

Subtract 2x from each side:

x = -6 .

\frac{3x-2}{8}= \frac{x}{4-1}
<em />
\frac{3x-2}{8}= \frac{x}{3}
<em>
Cross, Multiply :
</em>

3(3x-2) = 8x

9x-6 = 8x

9x - 8x - 6 = 0

9x - 8x = 6

\boxed{x = 6}



<em><u>Note :
</u></em><em>Remember this cross multiply formula :
</em>\frac{a}{b} = \frac{c}{d} \,\,\,\,\,\,\,\,\, \to \,\,\,\,\,\,\,\,\,(a \times d) = (b \times c)

If we go back to the defenition of logs, we can find this solution quickly.


What you're saying when you say ㏒₂(5x+7) = 5 is that

2⁵ = 5x+7

So

32 = 5x+7

25 = 5x

x = 5

AfilCa [17]

Answer:

Ok so lets break it down.

Step-by-step explanation:

5-2 = 3 now we have 1/4 and 1/10 10 divided by 4 = 2.5

So we can convert it then we have 2.5 out of ten.

then we add them up equals 3.5 out of ten.

Now we have 3.3.5  So now all we do is have to add 2.
