Answer: p = 0.25
Explanations:
The given equation is:
3(5 - p) - 2(5 + p) = 3(p + 1)
Step 1: Expand all the brackets
15 - 3p - 10 - 2p = 3p + 3
Step 2: Collect like terms ( That is, let everything that has p go together)
15 - 10 - 3 = 3p + 3p + 2p ( Note that the sign changes when anything crosses the equality sign)
2 = 8p
Step 3: Divide both sides by 8
2/8 = 8p/8
1/4 = p
p = 1/4
p = 0.25
