<span>Combine the logarithms first: log5(4x+3)-log5(x-1). Since it's subtract, divide the two.
log5((4x+3)/(x-1))=2
Make both sides the exponent of five. 5^log5 cancels out.
5^(log5(4x+3/x-1))=5^2
4x+3/x-1=25
Multiply both sides by (x-1) to get rid of it under 4x+3.
(x-1)4x+3/x-1=25(x-1)
4x+3=25x-25
Now subtract 4x from both sides AND add 25 to both sides. This way you'll have all the x's by itself.
28=21x
Divide both sides by 21.
28/21=x
x=1.33333333333...

Answer:
No, Jude’s graph is incorrect. The inequality symbol is “less than,” so -9 is not included. He should have used an open circle on -9.

sorry that im late on this, but i hope it helps anyone else : )
Given equation: 3(x + 4) + 2 = 2 + 5(x – 4).
<em>First step is to distribute 3 on left side and 5 on right side of the equation,</em> we get
3x + 12 + 2 = 2 + 5x – 20
<em>Second step is combining like terms, 12+2=14 and 2-20=-18.</em>
We get
3x +14 = 5x -18.
<h3>Third step, we need to get rid 18 from right side and 3x from left side.</h3>
<em>Adding 18 on both sides and subtracting 3x from both sides</em>, gives
32 = 2x.
<h3>Fourth step , we need to get rid 2 from right side from 2x.</h3>
<em>We need to divide both sides by 2</em>, we get
16=x.
