Responses

−8x+3=−8x+3
negative 8 x plus 3 equals negative 8 x plus 3

−3x+8=−3x−8
negative 3 x plus 8 equals negative 3 x minus 8

−3x−8=3x−8
negative 3 x minus 8 equals 3 x minus 8

3x−8=3x+8

Answer 1

-3x−8 = 3x−8

Solve: add 3x to both sides → −8 = 6x − 8, so 6x = 0 and x = 0.
(For the others: −8x+3=−8x+3 has infinitely many solutions; −3x+8=−3x−8 and 3x−8=3x+8 are contradictions, no solution.)
