Need |7z-7|+3=4x+1 a.5/3 and -5/3 b.5/3 and 9/11 c.9/11 and -9/11 d.-5/3 and -9/11

|7x-7|+3 = 4x+1  ⇒⇒⇒ add (-3) to both sides

∴ |7x-7| = 4x - 2

According to the absolute rule
∴ 7x - 7 = 4x - 2    OR    -(7x - 7) = 4x - 2                                 
    7x - 4x = 7 - 2      l     7x - 7 = -4x + 2                              
   3x = 5                   l     7x + 4x = 2 + 7                                         
  x = 5/3                   l     11 x = 9  ⇒⇒⇒  x = 9/11

∴ x = 5/3  and  9/11

So, the correct answer is option B. 5/3 and 9/11

Part A:4m + 12 + 20m

2 (2m + 6 + 10m)

Part B: 2 (2m + 6 + 10m) = 4(m + 3 + 5m)

4m + 12 + 20m = 4m + 12 + 20m

24m + 12 = 24m + 12

Part C: if m equals 2,

4(m + 3 + 5m)

compile it down

4(2 + 3 + 5 x 2)

4(5 + 5 x 2)

4(10 x 2)

4(20)

4 times 20

80
