It is simple
Step 1) substitute x = 5 into the equation
3x +4
3(5) + 4 gives you 3 times 5 + 4
The answer is 15 + 4 which is 19
Now substitute a and b into the equation 3(a) + 4(b) when the a = 6 and b = 5
Hereby 3(6) + 4(5)
3 * 6 = 18 and 4* 5 = 20
18 + 20 = 38
The answer is 38
Now finally
Substitute a and b Into the equation
3(3) + 4(6)
9+ 24 = 33
This is substitution, it's very simple once you get the hang of it!
okay, what you want to do is plug in the numbers you already have, to get the number you don't have(r).
First, you plug in the numbers.
1. P= $2000
A=$2543
t= 4(years)
r=?
2543=2000^r(4)
Secondly, you want to solve the equation.
Commission is earning a certain percentage of the total sold price.
To figure this out we need to find what is 3% of $120,000
We can do this by multiplying 3% and $120,000
First let's change 3% into a decimal.
3% = 0.03
Now lets multiply.
0.03 x $120,000 = $3,600
So this person earned $3,600 in commission.
Good Luck! :)

because they are exterior angles because they are on the outside and alternate because they are on opposite sides
