7q = 21
q = 3
Look at it this way: If p = 1, then 7p = 7. What plus 7 equals -3? Adding 7 to -10 would equal -3, so all we have to figure out is what times 5 would equal -10. 5 times -2 would equal -10 so q equals -2.
Q) -3-(+7)=-3-7 =-10
9q - 14 + 3q - 8 = 7 So 9q + 3q = 7 + 14 + 8 ie 12q = 29 so q = 29/12 = 2.41666..
21-q
In algebra, "twice q" refers to the expression that represents two times the variable ( q ). Mathematically, it is written as ( 2q ). This indicates that whatever value ( q ) takes, it should be multiplied by 2. For example, if ( q = 3 ), then "twice q" would equal ( 6 ).

-3 ≤ (6-q)/9 ≤ 3 -27 ≤ 6-q ≤ 27 -33 ≤ -q ≤ 21 -21 ≤ q ≤ 33 (the direction of inequalities change when multiplied by a negative number)

no.Matt says:For starters this open Q is badly written and the second part makes no sense in its current state!!Do you mean: a) "What is the large number and is it divisible?"OR b) "Which number is the large number divisible by?"OR c) "Is the large number divisible by 21?"Next whomever answered this first should not be trusted to answer Q's as not only did they NOT really answer the Q but they are WRONG!The Q states "the number is even", so it IS divisible by 2 at least.If the Q was in fact c) then (being an open question), here are some of the infinate answers:399, 3+9+9=21, 399/21=19, but it's not even.588, 5+8+8=21, 588/21=28777, 7+7+7=21, 777/21=37 not even.966, 9+6+6=21, 966/21=461596, 1+5+9+6=21, 1596/21=761659, 1+6+5+9=21, 1659/21=79 not even.1785, 1+7+8+5=21, 1785/21=85 odd1848, 1+8+4+8=21, 1848/21=881974, 1+9+7+4=21, 1974/21=942289, 2+2+8+9=21, 2289/21=109 odd.... and so on. ps I hate open questions!

There is absolutely no reason why the ratios P and Q should be equal!
It was not the last time I solved for q.
