So you want to solve for x?
It would be nice if this would easily factor:
(-4x + 5)(2x +1) = 0 This will not work!
So you need to use the quadratic formula:
a = -8, b = 4, c = 5

x = (-4 +/-

)/2(-8)
= (-4 +/-

)/-16
= (-4 +

)/-16
= 1/4 -

/4
Answer:
subtract 2x on both sides
Step-by-step explanation:
9:45 + 10 = 9:55
9:55 + 2:00= 11:55 This is what I got
