Question

solve the following pair of linear equation by substitution method, 2x+y=5 and 6x+3y=19​

Answer 1

Step-by-step explanation:

1st equation 2x+y=5

2nd equation 6x+3y=19

substituting y variable in terms of x

therefore, 2x+x=5

therefore, 3x=5

therefore, x=5-3

therefore, x=2

substituting x variable in terms of y

therefore, 6y+3y=19

therefore, 9y=19

therefore, y=19-9

therefore, y=10

answer: x=2 ; y=10
