VW = 9

VX is the whole line
VW and WX makes up VX so:
VW + WX = VW, or:
(4x - 7) + (3x) = (5x + 1); add 3x
7x - 7 = 5x + 1; subtract 5x
2x - 7 = 1; add 7
2x = 8; divide 2
x = 4

Now Put 4 in for VW:
(4(4)-7); multiply
(16-7)
9

5<br> ogarithmic equation in exponential form:<br> log(5k + 4) = 8r

alexandr1967 [171]

Given:

$\log (5k+4)=8r$

To find:

The exponential form of given equation.

Solution:

We have,

$\log (5k+4)=8r$

According to the property of the logarithm,

$\log_ax=y\Rightarrow x=a^y$

Using the above property of the logarithm, we get

$5k+4=10^{8r}$

Therefore, the required equation in exponential form is $5k+4=10^{8r}$ .
