Question

10p - 4 = 4(2p + 1); p = 2, 4, - 4​

Answer 1

Answer:

p=4

Step-by-step explanation:

put p=2

10(2)-4=4(2(2)+1)

20-4=4(4+1)

16=4(5)

16 not equal to 20

put p=4

10(4)-4=4(2(4)+1)

40-4=4(8+1)

36=4(9)

36=36

so p =4

Answer 2

$10p - 4 = 4(2p + 1) \\ 10p - 4 = 8p + 4 \\ 10p - 8p = 4 + 4 \\ 2p = 8 \\ p = \frac{8}{2} \\ p = 4$
