6p+11q+4
10p + 5p - p = 15p - p = 14p
If you mean: 5p = 30 then p = 6
5p-10 = 50 5p = 50+10 5p = 60 Divide both sides of the equation by 5 to find the value of p: p = 12

(p-3q) (p-3q) =p2+3pq+3pq+9q2 =p2+6pq+9a2 this is answer hehehhe (jhaylotte)
It is 2p + 3q. This is an expression and so cannot be solved. It cannot be simplified, and without information about the values of p and q, it cannot be evaluated.
P = 3a - 3q Add 3q to each side: P + 3q = 3a Double each side: 6a = 2P + 6q
7p + 2q = 46 . . . . (A) 5p + 3q = 36 . . . . (B) 3*(A): 21p + 6q = 138 2*(B): 10p + 6q = 72 Subtracting gives 11p = 66 so that p = 6 Substitute for p in (A): 7*6 + 2q = 46 or 42 + 2q = 46 which gives 2q = 4 so that q = 2 Solution: (p, q) = (6,2)
2p + 3q = 13, 5p - 4q = -2 Multiply the first equation by 4 and the second by 3 and add them, which gets rid of the q: 8p + 15p = 52 - 6, and 23p = 46, so p=2. Plug that into the first equation to find q: 4 + 3q = 13, so q=3. Test your answers in the second equation to be sure: 5(2) - 4(3) = 10-12 = -2. It checks. So p=2, q=3.
6p + 11q + 4
6p+11q+4
10p + 5p - p = 15p - p = 14p
3q + 2p
If you mean: 5p = 30 then p = 6
5p-10 = 50 5p = 50+10 5p = 60 Divide both sides of the equation by 5 to find the value of p: p = 12
