Solve the following pair of linear equations :
3x + 4y = 10
2x - 2y = 2​

Answer 1

Step-by-step explanation:

$3x + 4y = 10 \\ 2x - 2y = 2$

Multiplying Equation 2 With 2

We Get,

$4x - 4y = 4$

Now Eliminating Both The Equations

We Get,

$3x + 4y = 10 \\ 4x - 4y = 4$___________________

$7x = 14$

$x = 14 \div 7 \\ = 2$

Now Substituting The Value Of X In Eq2

We Get,

2×2-2y=2

4-2y=2

4-2=2y

2/2=y

Y=1

Answer :-

$x = 2 \\ y = 1$

Answer 2

Answer :

• Value of x = 2 and y = 1.

Given :

• Equations, 3x + 4y = 10

• 2x - 2y = 2

To find :

• The following pair of linear equations =?

Step-by-step explanation :

3x + 4y = 10 .... (i)

2x - 2y = 2 .... (ii)

Then,

2x - 2y = 2

So, x - y = 1

2 × equation (ii)

=> 4x - 4y = 4 ....... (iii)

Adding equation (i) and(iii), we get

7x = 14

x = 14/7

x = 2

Putting x = 2 in equation (i), we get

3(2) + 4y = 10

6 + 4y = 10

4y = 10 - 6

4y = 4

y = 4/4

y = 1

Hence, value of x = 2 and y = 1.
