The solution for given linear equation systems is (3,-4).
Option: C
<u>Step-by-step explanation:</u>
The given equations are 5x+3y=3 and x+y= -1.
Let us isolate x value from equation 5x+3y=3.
5x = 3-3y.
 .
.
Substitute this x value in equation x+y= -1.
 .
.
After taking LCM for the denominator,
 .
.
3-3y+5y=-5.
2y=-8.
y=-4.
For  substitute the y value.
 substitute the y value.
 .
.
 .
.
 .
.
x=3.
∴ The solution is (3,-4).

Ratio of their bases =  
 
 Ratio of their altitudes = 
<u>Step-by-step explanation:</u>
For first rectangle, it was given that 
Base 1 = 12 inches
Altitude 1 = 6 inches
For the second rectangle, it was given that
Base 2 = 10 inches
Altitude 2 = 5 inches
Ratio of their bases is given by the ratio of the base of the first rectangle to the second one. 
Ratio of their altitudes is given by the ratio of the altitude of the first rectangle to the altitude of the second rectangle.
 Ratio of their bases =  
 
 Ratio of their altitudes =
