Question

Q1.if y=1then find the value of x for equation 2x+y=5.
​

Answer 1

Explanation:

Given

We have given an equation 2x+y = 5

and value of y is 1

To Find

We have to find the value of x

$\sf\huge\bold{\underline{\underline{{Solution}}}} </p><p>Solution$

Since,y is given and an equation is given and have to find x so, we can easily find out the value of x by putting y's value into an equation and evaluate it.

➙2x+y= 5

put y into the Equation

➙2x+1=5

shift constant term to the constant side

➙2x= 5-1

➙2x= 4

Now,move 2 to constant side which is being multiplied with variable x.Now, it gets divide when shifts to constant side.

➙x= 4÷2

➙x= 2

Hence,value of x is 2

Check:

➙2x+y= 5

➙2(2)+1

➙4+1

=5

Since,LHS = RHS (verified)

Answer 2

Explanation:

y = 1

2x + 1 = 5

2x = 6

x = 6/2

x =3
