Answer:
Subtractionproperty of inequality.
Step-by-step explanation:
Expressed in scientific notation the answer would be 3.05 X 10^6
Let x = sue
and then let 3x-84 = marcia
therefore
(x)+(3x-84)=132
4x-84=132
4x=216
x=54
however just solving for x doesnt completely solve. it only shows sues money because x = sue
for marcia
3x-84
3(54)-84
162-84
78
therefore Marcia has 78$.
