What is the x-coordinate of the solution to the following system of equations?

x - y = -3
x + 3y = 5

Ox= -2
Ox= -1
Ox= 1
Ox= 2

a

step-by-step explanation:

x = 3 ± √(5+y)

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
