Question

Solve the following pairs of linear equations by the substitution method:
X+Y=14
X-Y =4

Answer 1

Answer:

x+y=14

x-y=4,then x=y+4

y+4+y=14

2y+4=14

2y=10

y=5

we know that x=y+4

x=5+4=9..

if my answer help you mark as brainliest....

Answer 2

Answer:

x= 9 and y= 5 is the required solution.
