Answer from: Quest
option 3 . (5x + 1) - (-10x + 6)
step-by-step explanation:
option 1 :
(4x + 3) + (-9x + 4)
or 4x+3 -9x + 4
or -5x + 7
option 2
(x - 2) - (6x - 9)
or x-2-6x + 9
or -5x + 7
option 3
(5x+ + 6)
or 5x + 1 + 10x -6
or 15x -5
option 4
-4x+2x+7-3x
-7x + 2x + 7
-5x + 7
hence only option 3 did not satisfy the given simplify expression.
