Question

A) (x/4)-1=1
B) (x-1/4)=1
C) (2x-1/3)=5
D) (x+1/5)=(x+1/2)
E) (2x+1/3)=(4x-1/5)

Answer 1

A) (x/4)-1=1
1X - 1 = 1
  4   1    1
X - 4 = 4
   4
X - 4 = 16
X=20

B) (x-1/4)=1

X-1 =1
  4
X-1 = 4
X=5

C) (2x-1/3)=5

2X-1 = 5
  3
2X-1 = 15
2X = 16
X = 8

D) (x+1/5)=(x+1/2)

X+1 = X+1
  5        2

2X+2=5X+5
-3X = 3
X = 3/-3
X = -1

E) (2x+1/3)=(4x-1/5)

2X+1 = 4X - 1
   3          5

10X+5=12X-3

2X=-8
X=-4
