Solution

Let's solve each of the linear equations step by step.

a. z13=5\frac{z - 1}{3} = 5

  1. Multiply both sides by 3 to get rid of the denominator: z1=15z - 1 = 15
  2. Add 1 to both sides to isolate zz: z=16z = 16

b. z+14=8\frac{z + 1}{4} = 8

  1. Multiply both sides by 4 to get rid of the denominator: z+1=32z + 1 = 32
  2. Subtract 1 from both sides to isolate zz: z=31z = 31

c. z42=4\frac{z - 4}{2} = -4

  1. Multiply both sides by 2 to get rid of the denominator: z4=8z - 4 = -8
  2. Add 4 to both sides to isolate zz: z=4z = -4

d. 6z7=0\frac{6 - z}{7} = 0

  1. Multiply both sides by 7 to get rid of the denominator: 6z=06 - z = 0
  2. Subtract 6 from both sides: z=6-z = -6
  3. Multiply both sides by -1 to solve for zz: z=6z = 6

e. 3z2=6\frac{3 - z}{2} = 6

  1. Multiply both sides by 2 to get rid of the denominator: 3z=123 - z = 12
  2. Subtract 3 from both sides: z=9-z = 9
  3. Multiply both sides by -1 to solve for zz: z=9z = -9

f. z5022=2\frac{-z - 50}{22} = -2

  1. Multiply both sides by 22 to get rid of the denominator: z50=44-z - 50 = -44
  2. Add 50 to both sides: z=6-z = 6
  3. Multiply both sides by -1 to solve for zz: z=6z = -6

Here are the solutions:

  1. z=16z = 16
  2. z=31z = 31
  3. z=4z = -4
  4. z=6z = 6
  5. z=9z = -9
  6. z=6z = -6
