Question

1. Solve x+y=14 and 2x-y=4 by substitution method​

Answer 1

Answer:

x=6 and y=8

Step-by-step explanation:

x+y = 14

y= 14-x

2x-y = 4

Substituting value of y in this equation

2x-(14-x) =4

3x-14=4

3x=14+4

x=18/3

x=6

Solving for y

x+y=14

6+y=14

y=14-6

y=8

Answer 2

Step-by-step explanation:

y=14-x

substituting the value of y in 2x-y=4

y=14-x

2x-14+x=4

2x=4+14

x=18/2

x=9

9+y=14

y=5
