Question

solve the following linear equations x = 4 upon 5 [x+10 ]

Answer 1

x=4/5(x+10)
5x=4x+40
hence x=40

Answer 2

solution:-

given by:-

$x = \frac{4}{5(x + 10)} \\ 5 {x}^{2} + 10x - 4 = 0 \\ ( - {b}^{2} ( + - ) \sqrt{ {b}^{2} - 4ac} ) \times \frac{1}{2a} \\ (- 100( + - ) \sqrt{100 - 80} \times ) \frac{1}{10} \\ (- 100( + - ) \sqrt{20} \times ) \frac{1}{10} \\ (- 50( + - ) \sqrt{5} \times) \frac{1}{5} \\ x = - 10 + \frac{1}{ \sqrt{5} } \\ \\ x = - 10 - \frac{1}{ \sqrt{5} }$
