Question

What is the value of p in the equation: 10p+9=8p+23

Answer 1

p = 7

Explanation:

10p + 9 = 8p + 23

Subtract 8p from both sides.

2p + 9 = 23

Subtract 9 from both sides.

2p = 14

Divide both sides by 2.

p = 7

Check:

10p + 9 = 8p + 23

Substitute 7 for p.

10 × 7 + 9 = 8 × 7 + 23

70 + 9 = 56 + 23

79 = 79

Since 79 = 79, the solution p = 7 is correct.
