Math Problem Statement

Select No Solution, One Solution, or Infinitely Many Solutions for each equation: 8v + 3 - 4v = 4v + 5 - 2, 7v - 11 = 7v + 11, 3(v - 4) = 2(v - 6), and 5(2v + 3) - 2 = 12v + 12 - 2v.

Solution

Let's go through each equation to determine whether it has no solution, one solution, or infinitely many solutions.

  1. 8v+34v=4v+528v + 3 - 4v = 4v + 5 - 2
    Simplify both sides: 8v4v+3=4v+38v - 4v + 3 = 4v + 3 4v+3=4v+34v + 3 = 4v + 3 Subtract 4v4v from both sides: 3=33 = 3 Since this is a true statement, the equation has infinitely many solutions.

  2. 7v11=7v+117v - 11 = 7v + 11
    Subtract 7v7v from both sides: 11=11-11 = 11 This is a contradiction, so the equation has no solution.

  3. 3(v4)=2(v6)3(v - 4) = 2(v - 6)
    Expand both sides: 3v12=2v123v - 12 = 2v - 12 Subtract 2v2v from both sides: v12=12v - 12 = -12 Add 12 to both sides: v=0v = 0 This equation has one solution.

  4. 5(2v+3)2=12v+122v5(2v + 3) - 2 = 12v + 12 - 2v
    Expand both sides: 10v+152=12v+122v10v + 15 - 2 = 12v + 12 - 2v Simplify: 10v+13=10v+1210v + 13 = 10v + 12 Subtract 10v10v from both sides: 13=1213 = 12 This is a contradiction, so the equation has no solution.
