Hi there!

Begin by distributing the 5:
5(2x) + 5(-12) = -90
Simplify:
10x - 60 = -90
Add 60 to both sides:
10x = -90 + 60
10x = -30
Divide both sides by 10:
x = -3
Answer:1/3
its 1/3 because 4 dived by 4 = 1 and 12 dived by 4 =3 so answer is 1/3
Since we know that he ate 1/4 pound one time, and 1/6 another time, we have to add up the fractions.
1/4+1/6
LCM of 4 and 6 = 12
3/12 + 2/12
Add the numerators:
5/12
So, he ate 5/12 of a pound of bars in both breaks.
Hope this helps!
