If jonny had 4 apples
and ate l, how many
does he have left?

left means subtracting/ minus

total apples - apples that have been eaten

4-1=3

answer:

he has 3 apples left.

answer: the answer is 3.

step-by-step explanation:

if he has 4 apples and ate one, subtract the amount he began with by the number that was consumed. 4 - 1 = 3.

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.
