First, combine like terms to get 4n-7=5n+1
add 7 to both sides to get 4n=5n+8
subtract 5n from both sides to get -n=8
multiply both sides by -1 to get an answer of n=-8
You will need 50 because 10 divided by 500 is 50 so you will need 50 markers.<span />
OK for number 3is 70because you add the number that they give you and then subtract 36 106 and you get your answer
X=62
Vertically opposite angles are equal
Y=44
Angles on a straight line add up to 180
Z =286
Because
180-x-y=74
360-74=286
