Question

how many solution of the following equation x+y=14,x-y=4​

Answer 1

Answer:

x=9 and y=5

Step-by-step explanation:

Let's solve your system by substitution.

x+y=14;x−y=4

Step: Solvex+y=14for x:

x+y=14

x+y+−y=14+−y(Add -y to both sides)

x=−y+14

Step: Substitute−y+14forxinx−y=4:

x−y=4

−y+14−y=4

−2y+14=4(Simplify both sides of the equation)

−2y+14+−14=4+−14(Add -14 to both sides)

−2y=−10

−2y/−2=−10/−2

(Divide both sides by -2)

y=5

Step: Substitute5foryinx=−y+14:

x=−y+14

x=−5+14

x=9(Simplify both sides of the equation)

Answer:

x=9 and y=5

plz plz plz follow me if the answer helpful to you

Answer 2

Answer:

x+y=14 and x-y=4

By adding both equations we get 2x=18,x=9

putting the value of x in eq 1 we get y=5
