Answer:
x=5, y=2
Step-by-step explanation:
Add the equations
x=y+3 → x - y =3 → 2x =10 → x=5 then → y =x - 3= 2
x+y=7 x+y=7
Answer:
x=-4 is true, x=6 is not
Step-by-step explanation:
5x + 7 < 22
Plug in our X values
5(-4) + 7 < 22 ?
solve
-20 + 7 < 22
-13 < 22 ?
x=-4 is true.
Repeat steps from ^
5(6) + 7 < 22
30 + 7 < 22
37 < 22 ?
x=6 is not true.
