Question

Identify the linear equations in two variables from the following A] under root3x + underroot5y=10 B]5x-0y-14=0 C]4/x+5/y=4 D]3xsqaure-7y=13

Answer 1

Answer:

Answer 2

Answer:

Answer-

( identity : (a-b)² = a²-2ab +b²)

= {(2x - 5y)}^{2}=(2x−5y)

2

= {(2x)}^{2} - 2(2x)(5y) + {(5y)}^{2}=(2x)

2

−2(2x)(5y)+(5y)

2

= 4 {x}^{2} - 20xy + 25 {y}^{2}=4x

2

−20xy+25y
