2/3 -4 x + 7/2 = -9x + 5/6

x= -2/3

Step-by-step explanation:

Add fractions (2/3, 7/2) 2/3+7/2=25/6

Move variable

Move constant

Collect like terms (-4x, 9x) -4x+9x=5x

Subtract the fractions 5/6-25/6=-10/3

Divide 5x=-2/3     x=-2/3

I'm not exactly sure how you want me to explain the answer but I hope that simplified answer helps.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
