Answer:
length = 7
width = 3
Step-by-step explanation:
the rectangle has four sides. All the sides added together give the 20 cm perimeter .
first find out the the approximate measurement of one side .
20÷4 = 5 cm
now you need to do addition and subtraction.
the width is 2cm less than the length
therefore the width = 5 - 2= 3cm
the length is 2cm more
therefore the length = 5 + 2 = 7 cm
7cm+7cm + (3cm ×2 ) = 20 cm .

Answer:
x = 6
y = -6
Step-by-step explanation:
x + y = 0 (Multiply by -1)
x + 9y= -48
-x - y = 0
x + 9y= -48
8y = -48
y = -6
x + y = 0
x - 6 = 0
x = 6
