$x = 9 \: and \: y = 5$

Answer 2

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)
