Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Answer:
ENGLISH SYSTEM:
What you want to do is simply convert the feet into inches for 1a. and for 1b. add the inches to the length and the width. For the rest of the English system, what you have to do is plug in the numbers.
METRIC SYSTEM:
So for this one it is the same thing but different measurements. Instead of converting feet to inches, you are converting meters to centimeters. Follow the same steps as you did with the English system.
Step-by-step explanation:
1a.
13*12=156
18*12=216
1b.
156+6=162
216+9=225
2.
162*225=36,450
3.
3.75*8=30
4.
36,450/30=1,215
1a.
4*100=400
5*100=500
2.
400*500=200,000
3.
9.5*20=190
4.
200,000/190≈1,053
