I need help solving the system of equations.
2x+y+z=10
2y+z=14
z+2

Answer 1

z+ 2 = ?

Answer 2

i reckon she means z=2

Answer 3

i concur with your reckoning

Answer 4

haha

Answer 5

if z=2

2y+2=14
2y=12
y=6

2x+y+z=10
2x+6+2=10
2x=2
x=1

Answer 6

Thank's!

Answer 7

2x+y+z=10---------(1)
2y+z=14-----------(2)
z=2--------------(3)

in equation '3'
z=2
put 'z' in equation (2)

2y+2=14
subract both sides by '2'
2y+2-2=14-2
2y=12
y=6
put y and z in equation '1'

2x+y+z=10
2x+6+2=10
2x+8=10
2x=2
x=1

Answer 8

Thank you!! I appreciate the help!
