B = 3m + 2p<br> Work out the value of p when B= 2 and m = 5
GarryVolchara [31]

This is called a "substitution problem" is where you have variable that have defined values and plug them in value calculate the expression.

B = 3m + 2p # Starting equation

2 = (3)(5) + 2p # Substitution

2 = 15 + 2p # Multiplication

-13 = 2p # Subtract 15 from both sides

\frac{-13}{2} = p # Divide both sides from 2

p = \frac{-13}{2} # Use the reflexive property of equality

Hope this helps!
