AB = 5
3x-4=5x-10
-3. -3
-4 = 2x -10
+10. +10
6 = 2x (divide by 2 on both sides)
X = 3

AB = 3x-4
3(3)-4 ( substitute for x)
9 - 4
= 5

3x-4=5x-10
Subtract 3x from both sides
-4=2x-10
Add 10 to both sides
6= 2x
X= 3
3 times 3-4
AB=5

Answer for the square root(5x-9)+1=x
Evgen [1.6K]

\bf \sqrt{5x-9}+1=x\implies \sqrt{5x-9}=x-1\implies 5x-9 = (x-1)^2 \\\\\\ 5x-9=\stackrel{\mathbb{FOIL}}{x^2-2x+1}\implies 5x=x^2-2x+10\implies 0=x^2-7x+10 \\\\\\ 0=(x-5)(x-2)\implies x= \begin{cases} 5\\ 2 \end{cases}
