X = number of lessons, y = total cost
y = 15x + 20 <== ur equation
when total bill was 125...y = 125
125 = 15x + 20
125 - 20 = 15x
105 = 15x
105/15 = x
7 = x <=== if Bill took 7 lessons, it would cost 125 <==

In this question, the first information that we get is that Kayla spent half of her weekly allowance in clothes. On cleaning the oven Kayla gets $4. Finally Kayla is left with $12.
Let us assume that the weekly allowance of Kayla = x
Amount of allowance saved after buying clothes = x/2
Then we can go for the equation
x/2 + 4 = 12
x + (4 * 2) = 12 * 2
x + 8 = 24
x = 24 -8
= 16
So we can now see that the weekly allowance of Kayla is $16
