Answer:
w = 7u/6
u = 6w/7
m = 2n/-9
n = -9m/2
Step-by-step explanation:
4u + 8w = -3u + 2w
4u - 4u +8w = -3u - 4u +2w
8w -2w = -7u + 2w - 2w
6w = -7u
w = 7u/6
u = 6w/7
AND
-2m - 5n = 7m - 3n
-2m -7m -5n = 7m -7m -3n
-9m -5n +5n = -3n +5n
-9m = 2n
m = 2n/-9
n = -9m/2

Answer:
10x + 8y = $200
Where y > 12
Step-by-step explanation:
Let x represent how many shirts he sells
y represent how many hats he sells.
John is doing a fundraiser for school. He needs to sell at least $200 worth of items. John is selling shirts for $10 each and hats for $8 each.
He must sell more than 12 hats.
y > 12
$10 × x + $8×y = $200
10x + 8y = $200
Where y > 12
The system of inequalities that model this situation is :
10x + 8y = $200
Where y > 12
