Multiply both sdies by 10 to get rid of the fractions
20(4x+3)/5-60(x-2)/2=5
4(4x+3)-30(x-2)=5
distribute
16x+12-30x+60=5
add like terms
-14x+72=5
subtract 72 from both sdies
-14x=-67
multiplyh -1
14x=67
divide both sdies by 14
x=67/14
Answer:
I got x= 1/5 and y= -67/25 (sorry if it is wrong)
Let x be how many hot dogs person b ate
therefore, person a ate x+8 hotdogs
and person c ate x-10 hotdogs
they all ate 130 hotdogs in total so
x + x + 8 + x - 10 = 130
3x -2 = 130
3x = 132
x = 44
so person b ate 44 hotdogs
person a ate 8 more so 52 hotdogs
and person c ate 10 less than person b so 34 hotdogs
Answer:
x = 5 or x = 2 or x = 0 or x = -3 thus 0 is the smallest root
Step-by-step explanation:
Solve for x:
x (x - 5) (x - 2) (x + 3) = 0
Split into four equations:
x - 5 = 0 or x - 2 = 0 or x = 0 or x + 3 = 0
Add 5 to both sides:
x = 5 or x - 2 = 0 or x = 0 or x + 3 = 0
Add 2 to both sides:
x = 5 or x = 2 or x = 0 or x + 3 = 0
Subtract 3 from both sides:
Answer: x = 5 or x = 2 or x = 0 or x = -3
