A) 7x+5 = 2x-35
-2x -2x
5x + 5 = -35
-5 -5
5x = -40
x = -8
b) x/3 - 7 = -5
+7 +7
x/3 = 2 .. Multiple by 3 both sides
x = 6
c) 4x+5 = 4x+1
-4x -4x
1 = 5 , This is
NOT true ..
NO SOLUTIONS

The answer is D. Because if it's 5x the width then make length 5x and width x so 12x because two lengths and two widths makes it 12x=96 divide and you get x=8 which means width is 8 cm
