First you collect like terms on each side.
X+(-8)=4x+1
Then you move the variable (x) to one side, and the constants to the other. (-x to both sides, and -1 to both sides)
-9 = 3X
Then you get the variable alone. (Divide by 3)
-3 = X
16x2 + 32x - 65 = 0 factorises (4x + 13)(4x - 5) This makes x either -13/4 or 5/4.
False. 65 equals 10 plus 65 65 = 10 + 65 65 = 75 You know that this is false because 65 doesn't equal 75.
65+35 = 100

98 plus 65 equals 163.
False. 65 equals 10 plus 65 65 = 10 + 65 65 = 75 You know that this is false because 65 doesn't equal 75.
30 and 41
65/65=1+65=66
55 + 27 + 65 = 147
65+35 = 100
