Answer:
x = 6
Step-by-step explanation:
Given
y = 
x - 3 and y = 11, thus
x - 3 = 11 ( add 3 to both sides )
x = 14
Multiply both sides by 3 to clear the fraction
7x = 42 ( divide both sides by 7 )
x = 6
Answer:
Lenght = 13, Width = 4
Step-by-step explanation:
Perimeter:
2(L + W) = 34
=> 2L + 2W = 34
Area:
L * W = 52
L = 2W + 5
L - 2W = 5
----------------------------
How to find the Length:
Now Add:
2L + 2W = 34
+ L - 2W = 5
-------------------------
3L = 39
L = 13
How to find the Width:
L * W = 52
13 * W = 52
W = 4
======================
Length = 13
Width = 4
