The answer is positive 9. Negative plus negaitve is a positive.
4p+9-7p+2 -3p+11 p = 11/3
4p+3 = -6p-5 4p+6p = -5-3 10p = -8 p = -0.8 Substituting the value of p into the original equation gives you: -1/5 = -1/5
8p+2=4p-10 8p-4p=-2-10 4p=-12 p=-12/4 =-3
p=-3
The answer is positive 9. Negative plus negaitve is a positive.
3(p+7) - (4p-1) = -5(2p-3) + 1 Multiplying out the brackets: 3p + 21 - 4p + 1 = -10p + 15 + 1 Simplifying: 22 - p = 16 - 10p 9p = -6 p = -2/3 To check, you could substitute p = -2/3 into the original equation and check that it holds.
4p+9-7p+2 -3p+11 p = 11/3
15 + 3 = 7p - 4p ie 18 = 3p so p = 6
5t+15
4p+3 = -6p-5 4p+6p = -5-3 10p = -8 p = -0.8 Substituting the value of p into the original equation gives you: -1/5 = -1/5
8p+2=4p-10 8p-4p=-2-10 4p=-12 p=-12/4 =-3
-3+4p-2p=1 -3+2p=1 2p=4 p=2
p=-3
p = -1
5t + 2 = 3t - 2t + 5 Collect like terms 5t - 3t + 2t = 5 - 2 4t = 3 t = ¾ Check: 5 x 3/4 = 3¾ + 2 = 5¾; 3x¾- 2x¾ + 5 = 5¾ QED
Answer = 2 - (-3) = 2 + 3 = 5 minus minus means plus.
