First of all we will squaring all the terms = (√5x)² - (√7y)²=0 , (√7x)² - (√3y)²=0 After that is becomes = 5x–7y=0 -this will be equation 1 7x–3y = 0 -this will bhi equation 2 We multiply equation 1 from 7 and equation 2 from 5 Then it eq 1×7 subtract eq 2×5 Eq 1- +35x – 49y = 0 Eq 2- ± 35x ± 15y = 0 ————————— 0 34y = 0 Y = 34 Now we put the value of 'y' in eq 1 5x–7y = 0 5x–7×34 = 0 5x–238 = 0 X = 238/5 X = 47.6 Y = 34
