a) x + 5 = 7
x + 5 - 5 = 7 - 5 (Subtract 5 from both sides)
x = 2
b) 2x - 8 = 20
2x - 8 + 8 = 20 + 8 (Add 8 to each side)
2x = 28
2x/2 = 28/2 (Divide each side by 2)
x = 14
c) 4x - 6x = 200
-2x = 200
-2x/-2 = 200/-2 (Divide each side by -2)
x = -100 (Note that a negative number divided by a negative number is positive, whereas a positive number divided by a negative number is negative)
d) x + 1 = 5
x + 1 - 1 = 5 - 1 (Subtract 1 from each side)
x = 4

these are our pure definition questions.
9. false
if the data was only defined for whole numbers, then that would be the only case, where that is true. but then, there would be no rounding.
the "significant figures" are the decimal places after the decimal point.
rounding it to one significant figure means rounding it to the first position after the decimal point.
10. True
see 9. for more details.
