Answer:
Numbers are 9 and 5
Step-by-step explanation:
x + y = 14
x - y = 4
Rewrite 1st equation
x = 14 - y
Put this into the other
14 - y - y = 4
14 - 2y = 4
14 = 4 + 2y
10 = 2y
<u>y = 5</u>
<u />
x + 5 = 14
<u>x = 9</u>
<u>Check answers both equations!!</u>
9 + 5 = 14 Correct
9 - 5 = 4 Correct
10
10+4 is 14 amd 14-4 is 10
2z^2-5z-63
