Determine the equivalent system for the given system of equations: 5x + 3y = 1 4x − 5y = 4 5x + 3y = 1 8x − 10y = 4 5x + 3y = 1 9x − 2y = 5 −5x − 3y = 1 4x − 5y = 4 2x + 3y = 7 9x − 2y = 4

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
