Answer:
Equation to be solved: 2+3x=15.5
The solution we want is: 4.5 million
The solution for p is: p=4.5
Step-by-step explanation:
The problem says:
15.5 million is 2 million more than 3 times the population in 1950.
We can write this as an equation like this:
15.5 million = 2 million + 3(x million).
Each term contains the factor of million so if we divide both sides by a million the equation can actually be written as:
15.5 =2 + 3(x)
15.5 =2 + 3x
So the equation we need to solve is:
15.5=2+3x
We want to isolate 3x. To do this we need to subtract 2 on both sides:
15.5=2+3x
-2 -2
-----------------
13.5= 3x
Divide both sides by 3:
13.5/3 = 3x/3
Simplifying both sides gives:
4.5=x
So 4.5 million is the population in 1950's.
