\frac{1}{169}X+1=\frac{100}{169}
Square both sides of the equation.
\frac{1}{169}X+1-1=\frac{100}{169}-1
Subtract 1 from both sides of the equation.
\frac{1}{169}X=\frac{100}{169}-1
Subtracting 1 from itself leaves 0.
\frac{1}{169}X=-\frac{69}{169}
Subtract 1 from \frac{100}{169}.
\frac{\frac{1}{169}X}{\frac{1}{169}}=-\frac{\frac{69}{169}}{\frac{1}{169}}
Multiply both sides by 169.
X=-\frac{\frac{69}{169}}{\frac{1}{169}}
Dividing by \frac{1}{169} undoes the multiplication by \frac{1}{169}.
X=-69
Divide -\frac{69}{169} by \frac{1}{169} by multiplying -\frac{69}{169} by the reciprocal of \frac{1}{169}.
