To solve the equation \( \sqrt{7 + 2x - 1} = 10 \), let's first simplify the left side.
The equation can be rewritten as:
\[
\sqrt{6 + 2x} = 10
\]
Next, we'll square both sides to eliminate the square root:
\[
6 + 2x = 10^2
\]
This simplifies to:
\[
6 + 2x = 100
\]
Now, we can isolate \(2x\) by subtracting 6 from both sides:
\[
2x = 100 - 6
\]
\[
2x = 94
\]
Next, divide both sides by 2 to solve for \(x\):
\[
x = \frac{94}{2}
\]
\[
x = 47
\]
Thus, the solution to the square root equation is:
\[
x = 47
\]
