Question

Find the value y in the equation 2x+y=7,if x=2 find x if y=1

Answer 1

Answer:

X=3 y=3

Step-by-step explanation:

2(2)+y=7

Y=3

2x+1=7x=3

Answer 2

Answer:

The value of y = 3 and x = 3.

Step-by-step explanation:

Given that:-

$2x+y=7$

If, $x=2$

We have to find the value of y for the expression,

( a ). Now, put the value of x as 2 in the expression:

=> $2(2)+y=7$

Simplifying it further, we get

=> 4 + y = 7

Rearrange the terms, we get

=> y + 4 = 7

Subtract both sides by $4$, we get

=> y + 4 - 4 = 7 - 4

=> y = 3

So, the value of y is 3.

( b ).  Now, put the value of y as 1 in the expression:

=> $2x+(1)=7$

Subtract both sides by $1$, we get

=> $2x+1-1=7-1$

$=> 2x=6$

Divide both sides by $2$, we get

$=> x = 3$

So, the value of x is 3.
