Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Arley is building a model of a city map. in one part of the city, three roads form a right triangle, which harley draws as triangle abc, with the following measures: m∠b=90° and m∠a=30°. in his scale model, the hypotenuse of triangle abc, ac¯¯¯¯¯¯¯¯, has a length of 817−−√ cm. what is the value of a (the length of bc¯¯¯¯¯¯¯¯)?

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10
