Answer:
x = 8, y = 3
Step-by-step explanation:
3x - 12y = 60
x + 2y = 14
3x - 12y = 60
3x + 6y = 42 (multiply by 3 so the x is the same as the top equation)
6y = 18 (subtract the equations)
y = 18 / 6
= 3
To find x, substitute y into the 2nd equation since it is the simplest so:
x + 2(3) = 14
x + 6 = 14
x = 14 - 6
= 8
Answer:
2,36<y
Step-by-step explanation:
-4<4(6y-12)-2y
4+48<22y
52<22y
22 22
2.3<y
Answer:
6 Quarters and 18 Dimes
Step-by-step explanation:
18 x 0.10 = $1.8
6 x 0.25 = $1.5
$1.5 + $1.8 = $3.30
