Math Problem Statement

Solve the linear equations g: 2x - 7 = -4, h: 2x - 11 = 23, i: 7 + 8x = -9, j: 6 + 3x = 0, k: 8 + 13x = 34

Solution

Let's solve each of these linear equations step-by-step.

Problem g: 2x7=42x - 7 = -4

  1. Add 7 to both sides:
    2x=32x = 3
  2. Divide both sides by 2:
    x=32x = \frac{3}{2} or x=1.5x = 1.5

Problem h: 2x11=232x - 11 = 23

  1. Add 11 to both sides:
    2x=342x = 34
  2. Divide both sides by 2:
    x=17x = 17

Problem i: 7+8x=97 + 8x = -9

  1. Subtract 7 from both sides:
    8x=168x = -16
  2. Divide both sides by 8:
    x=2x = -2

Problem j: 6+3x=06 + 3x = 0

  1. Subtract 6 from both sides:
    3x=63x = -6
  2. Divide both sides by 3:
    x=2x = -2

Problem k: 8+13x=348 + 13x = 34

  1. Subtract 8 from both sides:
    13x=2613x = 26
  2. Divide both sides by 13:
    x=2x = 2

Summary of Solutions

  • g: x=1.5x = 1.5
  • h: x=17x = 17
  • i: x=2x = -2
  • j: x=2x = -2
  • k: x=2x = 2
