A triangle with three congruent sides is an equilateral triangle. An equilateral triangle's all sides are always equal to each other, and the angles are also congruent.
Pre tax in first city = x
pre tax in 2nd city = x - 500
0.09x + 0.095(x - 500) = 970
0.09x + 0.095x - 47.5 = 970
0.09x + 0.095x = 970 + 47.5
0.185x = 1017.50
x = 1017.50/0.185
x = 5500 <== first city
5500 - 500 = 5000 <== 2nd city
