SOLUTION
Draw the diagram
a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.
Hence

SInce AC=30, Then

Thus, from the median properties of a triangle, AB = 15

Answer:
Solving Two-Step Equations
1) First, add or subtract both sides of the linear equation by the same number.
2) Secondly, multiply or divide both sides of the linear equation by the same number.
3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable
