Answer 2

Answer:

The variable: 8p - 9=5p +6   p=5

Step-by-step explanation:

Step : 1 5x + 9 = 5 + 3x5x + 9 = 5 + 3x 5x = 3x + 5 − 9 5x = 3x − 4 5x − 3x = −4 2x = −4 x = (−4)/2 x = −2 Check:- L.H.S 5x + 9 = 5 (−2) + 9 = −10 + 9 = −1 R.H.S 5 + 3x = 5 + 3 (−2) = 5 − 6 = −1 ∴ LHS = RHS Hence Verified.

Therefore, n = 2 is a solution of the given equation, 7n + 5 = 19. As L.H.S ≠ R.H.S., Therefore, p = 1 is not a solution of the given equation, 4p − 3 = 13.

Step : 2 8p-9=5p+6

8p-9+9=5p+6+9

8p=5p+15

8p-5p=5+15-5p

3p=15

3p/3=15/3

p=5
