Answer:
x=-4/V
Step-by-step explanation:
Add 4 to both sides to cancel out the 4.
So it now the equation is Vx+9=5
Subtract 9 from both sides to cancel out the 9.
Now the equation is Vx=-4
Divide V to both sides to get x alone.
The answer being x=-4/V
For this case we must find the value of "x" of the following equation:
[tex]\sqrt {x + 9} -4 = 1[/tex]
We add 4 to both sides of the equation:
[tex]\sqrt {x + 9} = 4 + 1\\\sqrt {x + 9} = 5[/tex]
We raise both sides of the equation to the square to eliminate the radical:
[tex]x + 9 = 5 ^ 2\\x + 9 = 25[/tex]
We subtract 9 from both sides of the equation:
[tex]x = 25-9\\x = 16[/tex]
Answer:
[tex]x = 16[/tex]
