    4+7y-10

    7y+4-10

    7y+-6

    7y-6

    14x+16xy-17xy+8x

    14x+-y+8x

    14x-y+8x

    14x+8x-y

    22x-y

    Good Luck!

    This is the easy stuff. Learn this now so you be screwed for the lYrr stuff. But all it basically is is just adding like terms. For your first problem. 4+7y-10 you subtract 4 from 10 and then put it as 6+7y and theres your answer. And the second one is the same. Just subtract 17xy from 16xy and then add 14x and 8x and then write it as 22x+xy

    Combine like terms, so on the first one add 4 and -10 so it will be 7y - 6,,, and do the same on the next one, 16xy can combine with -17xy to make a -xy and 14x can combine with 8x to make 22x so your answer is 22x - xy

    4+7y-10

    combine like terms

    7y -10+4

    7y-6

    then 7y=6

    y=6/7

    and

    14x+16xy-17xy+8x

    combine like terms

    14x+8x +16xy-17xy

    22x-xy

    then

    you can factor out an x

    x(22-y)

    you got to combine like terms, so on the second one if you combined 8x and 14x it would be 22x +16xy-17xy. If you need to find the actual value of the variable then you would need to use substitution.

    That means you would have to get either x or y all by itself and then find the other variable

    first one.

    combine like terms.

    so it would be 4 + -10 to get -6

    so you would get -6+7y

    second one.

    combine like terms.

    so you combine 16xy and -17xy to get -1xy

    and then you combine 14x and 8x to get 22x so your answer is

    22x-1xy or just 22x-xy

    You have to figure out how fast he is going, Miles per hour like, So how many times can 8 go into 464? that will tell you the MPH, then multiply that by 5 1/2. same with the second question, it's the same concept.

    for the first one, i'm assuming it equals 0, so first

    add 4 and -10

    7y-6=0

    7y=6

    y=6/7

    2nd one.., I think you're supposed to factor it so...

    14x+8x+16xy-17xy

    22x-xy

    x(22-y)

    If these are equal to 0 from that property, then

    x=0

    22-y=0

    y=22
