Given the equation:
3p + 4 + p + 12 + 39
Determine the equivalent expression.
Solution:
In order to determine the equivalent expression, we simply need to combine like terms.
= 3p + 4 + p + 12 + 39
= 4p+ 55
If we are asked to find for p, we need to transpose 55 to the other side of the equation, and then divide both sides by 4. Hence it must be taken to note that in transposing a number, the sign changes.
4p = -55
4p/4 = -55/4
p = -13.75
Final answer:
= 4p + 55
- = -13.75
