Answer:
Sheila had $300 at first
Step-by-step explanation:
Given that:
Sheila spent:
for coat = $120
Let the original money be x so,
dress for = $(2/3(x - 120 ))
Now she left with = 1/5x
Now by adding all the amounts we get the original amount x:
x = 120 + (2/3(x - 120)) + 1/5x
By simplifying:
x = 120 + 2/3x - 240/3 + 1/5 x
adding like terms:
x = 120 - 80 + 2/3*5/5x + 1/5*3/3x
x = 40 + (10+3)x/15
x = 40 + 13x/15
x - 13x/15 = 40
Taking LCM
(15x - 13x)/15 = 40
2x/15 = 40
Multiply both sides by 15/2
x = 40*15/2
x = $300
so Sheila had $300 at first

Answer:
B. There is no solution; x and y are eliminated and you get the false statement 0 = 20.
Step-by-step explanation:
According to the elimination method, the two equations are
y + 3x = 10
−y − 3x = 10
If we solve it
0 = 20
As x and y would be eliminated due to positive and negative signs
Therefore the option b is correct
