Question

Form the equation of y=3x find x if y=-3

Answer 1

Step-by-step explanation:

y = 3x means 3x = y

Value of y is -3.

Solution,

$\: \: \: \: \: \: y = 3x$

$= > 3x = y$

$= > 3x = - 3$

$= > x = \frac{ - 3}{3}$

$\: \: \: \: \: \: \: \: \: \: \: \: = - 1$

Hence, value of x is -1.

Answer 2

Answer:

⇒ 3 x - y = 0

x = - 1 .

Step-by-step explanation:

Given :

y = 3 x

Equation ⇒ 3 x - y = 0

Now we have 3 x - y = 0

Given  y = - 3

Put the value of y = - 3 in equation we get

3 x - y = 0

3 x - ( - 3 ) = 0

3 x + 3 = 0

3 x = - 3

x = - 3 / 3

x = - 1 .

Thus we get x = - 1 .
