Answer:
x = 65/16, y = 37/16
Step-by-step explanation:
solve the system algebraically
x+3y=11
4x-4y=7
Try substitution.
let x = 11 - 3y
Plug in.
4(11 - 3y) - 4y = 7
44 - 12y - 4y = 7
44 - 16y = 7
37 = 16y
y = 37/16
x = 11 - 3*y
x = 11 - 3*(37/16)
x = 11 - 111/16
x = 65/16
Answer: 33 and 28
Step-by-step explanation:
so, all we know is ? + ? = 61
if the larger number is 5 more than the smaller number, we can assume that..
33 + 28 = 61
No, the slopes are not equal
Answer:
14 > 12
Step-by-step explanation:
2(3b+7) - 6b > 12
6b + 14 - 6b > 12
14 > 12
