This problem is unit rate!
Basically, it is 12/6
So each donut is $2 !
there should be a cross multiplication
3(8x)=2
expanding bracket
24x=2
multiple both sides by 24
x=1/12
Answer:
x = -4
Step-by-step explanation:
8x = 8 + 2(x-10) + 3x
simplify
8x = 8 + 2x - 20 + 3x
simplify again
8x = 5x - 12
subtract 5x from both sides
3x = -12
divide both sides by 4
x = -4
