Question

Solve the following pair of linear equations by the elimination method (i) 2x+y=7 ; 2x-2y=-2

Answer 1

Step-by-step explanation:

Answer:

(2, 1)

Step-by-step explanation:

3x + 4y = 10

2x - 2y = 2

let's multiply second equation by 2 and add to first equation, we eliminate "y"

3x + 4y = 10

4x - 4y = 4

7x = 14

x = 2

3×2 + 4y = 10

4y = 10 - 6

y = 1
