Answer:
Isolate Square Root:
Isolate the
square root
on one side of the equation by subtracting
19
19
19
from both sides.

\sqrt{7x - 34} = 1
7
x
−
34
=
1
Square Both Sides:
Square both sides of the equation to eliminate the square root.

Add
34
34
34
:
Add
34
34
34
to both sides of the equation to isolate the term with the variable
x
x
x
.
\newline
7
x
−
34

\newline
7
x
=

7x = 35
7
x
=
35
Divide by
7
7
7
:
Divide both sides of the equation by
7
7
7
to solve for
x
x
x
.
