Answer:
a) all real numbers
b) v = -2.5
Explanation:
a) 2x - 1.5 = 2x - 1.5
subtract 2x from both sides of the equation
2x - 1.5 - 2x = 2x - 1.5 - 2x
1.5 = 1.5
since 1.5 will always equal 1.5 regardless of what x is,
the solution is all real numbers
b) 2v + 4 = -1
subtract 4 from both sides of the equation
2v + 4 - 4 = - 1 - 4
2v = -5
divide both sides of the equation by 2
2v/2 = -5/2
v = -2.5
