Question

Solve the following pair of linear equations by substitution and elimination method
3x + 4y = 10 and 2x - 2y = 2

Answer 1

Answer:

3x+4y=10

2x-2y=2

Step-by-step explanation:

here first eq to be multiplied with1and eq2with 2..

so it would be like this..

6x+4y=10

4x-4y=4..y will be cancelled

so it would be like this..

10x=14 ans=7/2... follow me

Answer 2

Answer:

elimination method is used to solve the question
