Answer:
<em>x = 1</em>
<em>y = 1</em>
Step-by-step explanation:
<u>System of Equations</u>
We are given the system of equations:
2x + y = 3
x = 2y - 1
Substituting x in the first equation:
2(2y - 1) + y = 3
Operating:
4y - 2 + y = 3
5y = 3 + 2
y = 5/5 = 1
y = 1
Since:
x = 2y - 1
Then:
x = 2(1) - 1
x = 1
Solution:
x = 1
y = 1

Answer:
Step-by-step explanation:
Isabell, can you see that the sides are 2x6 each? each half of the triangle will make a total rectangle of 2x6 or 12 square meters
there are 4 of those so 48 sq meters plus the base of 4x4 or 16 sq meters
48+16 = 64 square meters total
