Question

x-3y =1 ,Find x when y=3. *​

Answer 1

Given:

$y=3$

To find:

The value of $x$.

Solution:

$\longrightarrow{\green{}}$ $x - 3y = 1$

Since the value of $y$ is known to us, just plug it in the above expression.

$\longrightarrow{\green{}}$ $x - 3(3) = 1$

$\longrightarrow{\green{}}$ $x - 9 = 1$

Adding both sides by 9 gives us

$\longrightarrow{\green{}}$ $x = 10$

Therefore, the value of $x$ is $\boxed{ 10 }$.

Answer 2

✡10☑

Step-by-step explanation:

Given⤵

• x-3y=1
• y=3

To find⤵

• Value of x.

Solution⤵

➡x-3y=1

⚫Putting the value of y= 3 in equation, we get

➡x-3×3=1

➡x-9=1

➡x=1+9

➡x=10

✅Hence,value of x is 10 .

Proof⤵

➡x-3y=1

⚫Putting the value of x=10 and y=3,we get

➡10-3×3=1

➡10-9=1

➡1=1

LHS=RHS
