Question

help me with this quiz!?

Answer 1

i think the first is {3}

Answer 2

do i cross multiply or distribute a common factor?

Answer 3

correct you cross multiply then perform inverse operations

Answer 4

but yes. 3=x

Answer 5

so i would have. 10x = 3(x+7) ?

Answer 6

yes. then distribute the 3. then subtract 3x both sides then divide both sides by 7 to get 3

Answer 7

remember.. inverse operations

Answer 8

oh see i though it wanted me to make it equal to zero again

Answer 9

this one i think is c

because: -36x = 9(x+10)
-27 x = 90
= - 3.333 so {-3/10}
