Answer:
L - W = 2 and 2L + 2W = 68
Step-by-step explanation:
The two equations here are going to be-
Length minus width equals 2
L - W = 2
And
Length x 2 + Width x 2 = 68
2L + 2W = 68

Answer:
z = 8.2
Step-by-step explanation:
6.7z = 5.2z + 12.3
combine like terms by subtracting 5.2z from both sides
1.5z = 12.3
divide by 1.5
z = 8.2
