7p + 2 = 5p + 8 7p - 5p = 8 - 2 2p = 6 p = 3
7p-10p = -3
4p+9-7p+2 -3p+11 p = 11/3
it is -7p + 32: exactly as in the question!

7p + 2 = 5p + 8 7p - 5p = 8 - 2 2p = 6 p = 3
7p-10p = -3
4p+9-7p+2 -3p+11 p = 11/3
5p + 15p + 7p = 27p 5p - 15p + 7p = -3p 5p x 15p + 7p = 75p2 + 7p 5p/15p + 7p = 7p + 1/3
it is -7p + 32: exactly as in the question!

15 + 3 = 7p - 4p ie 18 = 3p so p = 6
7p + 3
If X is the variable, then X/(-12+9) = x/(-3) = -X/3
-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r
