Answer:
(1, -2)
Step-by-step explanation:
Subtracting the first equation from the second gives ...
(5x +y) -(3x +y) = (3) -(1)
2x = 2 . . . . . collect terms
x = 1 . . . . . . . divide by 2
Then substituting into the first equation, we have ...
3·1 +y = 1
y = -2 . . . . . . subtract 3
The solution is (x, y) = (1, -2).
This is a proportion problem. Set up your equation:
8/96 = 7/x
Now cross multiply
96 x 7 = 672
672/8 = 84
Answer is $84
Answer:
x ≥ 1/2
Step-by-step explanation:
6x + 21 ≥ 24
6x ≥ 3
x ≥ 1/2
check: (1/2 x 6) + 21 = 24
