4p + 9 - 7p + 2 4p - 7p + 9 + 2 p(4 - 7) + 9 + 2 -3p + 11
3p +12= 7p 7p-3p=12 12?3=4 p=4
7+5q = -3 5q = -3-7 5q =-10 q = -2
7p-2p equals = 5
7p+5q=-3, p=1 7Xp+5q=-3 7+5q=-3 5p=-10 p=-2
4p + 9 - 7p + 2 4p - 7p + 9 + 2 p(4 - 7) + 9 + 2 -3p + 11
3p +12= 7p 7p-3p=12 12?3=4 p=4
7+5q = -3 5q = -3-7 5q =-10 q = -2
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.
8p+5 = 11+7p= 8p-7p = 11-5p = 6
Those elements were (till now) not found
3p - 8 = 13 - 4p : Add 4p to both sides 7p - 8 = 13 : Add 8 to both sides 7p = 21 : Divide both sides by 7 p = 3.
7P + 9 = 16 + 6P subtract 6P from BOTH sides P + 9 = 16 subtract 9 from both sides P = 7
14 + 6p = 6 + 7p 8 = p
7p + 2 = 5p + 8 7p - 5p = 8 - 2 2p = 6 p = 3
