Solve by elimination method√5x - √7y = 0√7x - √3y = 0Find the value of x and y |
| Answer» First of all we will squaring all the terms = (√5x)² - (√7y)²=0 ,(√7x)² - (√3y)²=0After that is becomes = 5x–7y=0 -this will be equation 17x–3y = 0 -this will bhi equation 2We multiply equation 1 from 7 and equation 2 from 5 Then it eq 1×7 subtract eq 2×5Eq 1- +35x – 49y = 0Eq 2- ± 35x ± 15y = 0 ————————— 0 34y = 0Y = 34Now we put the value of \'y\' in eq 15x–7y = 05x–7×34 = 05x–238 = 0X = 238/5X = 47.6Y = 34 | |
