Answer: x= 5
Step-by-step explanation:
Plug the second equation into the first equation’s y.
3x-2(-2x+7)=21
Then use distribution
3x+4x-14=21
Add 4x and 3x
7x-14=21
Then add 14 to both sides
7x=35
Divide by 7 to get x
35/7=5
x=5

-6 -6
8x=48
8x /8=48/8
x=6 the bracelets were $6 a piece
1/2 or 0.5 x 3/4 or 0.75 = 0.375 or 3/8
