Question

how many solutions y=2x have? write four solutions of this equations​

Answer 1

Step-by-step explanation:

y=2x

let x=1

y=2×1

y=2

Let x=2

y=2×2

y=4

Let x=3

y=2×3

y=6

Let x=-2

y=2×-2

y=-4

Answer 2

Answer:

$y=2x$

$0=2$ × $x$

$0 = x$

$x=0$  

$Let \ y = 2x$

$2=2x$

$\frac{2}{2} =x$

$1=x$

$x=1$

$Let \ y =-1$

$-1=2x$

$-\frac{1}{2} = x$

$x = -\frac{1}{2}$

$Let \ y = 4$

$4=2x$

$\frac{4}{2} \ = \ x$

$2 = x$

$x=2$
