Question

Solve the following pair of equations by substitution method :
x + y = 14
x - y = 4.​

Answer 1

Step-by-step explanation:

Using substitution in the above equations....

x + y = 14

x = 14 - y

Substituing it in the 2nd equation

x - y = 4

14 - y - y = 4

14 - 2y = 4

18 = 2y

y = 9

Substitutimg this value in 1st equation

x = 14 - 9

x = 5

Answer 2

Answer:

y=5

x=9

Step-by-step explanation:

x=14-y

x-y=4

14-y-y=4

-2y. =4-14

-2y. =-10

y. = 5
