The expression (4p - 5t + 3) represents a linear combination of the variables (p) and (t). To evaluate it, you would need specific values for (p) and (t). Without those values, the expression remains in its algebraic form.
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
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
5t+15
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

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
p = -1
p=-3
