7P + 9 = 16 + 6P subtract 6P from BOTH sides P + 9 = 16 subtract 9 from both sides P = 7
-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r
-31=8-6p-7p -31=8-13p ==add the -6p and the - 7p together -39=13p =======move the 8 over to the other side p=3 =======divide both sides by 13 to get p by itself
8p+5 = 11+7p= 8p-7p = 11-5p = 6
7p + 2 = 5p + 8 7p - 5p = 8 - 2 2p = 6 p = 3
7P + 9 = 16 + 6P subtract 6P from BOTH sides P + 9 = 16 subtract 9 from both sides P = 7
-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r
-31=8-6p-7p -31=8-13p ==add the -6p and the - 7p together -39=13p =======move the 8 over to the other side p=3 =======divide both sides by 13 to get p by itself
To solve this group together the like terms. 7p + -p = 6p Then the answer is 6p -9.
-318-13p
8p+5 = 11+7p= 8p-7p = 11-5p = 6
7p + 2 = 5p + 8 7p - 5p = 8 - 2 2p = 6 p = 3
4p+9-7p+2 -3p+11 p = 11/3
4p + 9 - 7p + 2 4p - 7p + 9 + 2 p(4 - 7) + 9 + 2 -3p + 11
11p+11
7p-2p equals = 5
Equilibrium occurs where Qd = QsQd - 128 + 9p = 0Qd = 128 - 9pQs + 32 - 7p = 0Qs = 7p - 327p - 32 = 128 - 9p16p = 160p = 10
