zlopas [31]

Answer:

W=5.3, l= 15.6

Step-by-step explanation:

Perimeter of a rectangle p=2(l+w)

P= 42

W= x

L= 5+2x therefore 42=2(5+2x+x)

42=10+6x , 32=6x

Make x subject of formula

X=32/6 x=5.3 there for w=5.3

Where L= 5+2x ; L=5+2(5.3)

L therefore = 15.6

Ok so the first step would be to distribute 3 into 3x and -6. So 3 times 3x would be 9x. 3 times -6 is -18. 

the equation now is 
18 = 9x - 18

Now you would have to do inverse operation 

18 = 9x - 18
+18       +18

36 = 9x 

Now you would divide 9x into 36 to isolate the variable

36 / 9x = 4
x = 4
