Start with parenthesis so that will be 7x -21so then  you will get 4x = 7x -21 then you will subtract 7x and 4x and you will get -3x = -21 and your answer is 7 because both numbers are a negative and that will equal a positive.

a rectangle plot measure 20ft. by 30ft. A 3-ft.-wide sidewalk surrounds it.Find the area of the sidewalk.
goldenfox [79]
Area of a rectangle = length (l) * width (w)
A = 30ft * 20ft
A = 600 sq ft

Now the width of a sidewalk that surroundeds it = 3 ft
so now the area of the rectangle with sidewalk= 30+3ft * 20+3ft
A = (33*23) ft
A = 759 sg ft

Area of the sidewalk = 759 - 600
A = 159 sq ft
