52 x 1.05 = $54.60
+ $4.37 (taxes) = $58.97
3 $20 bills is $60 so $60 - $58.97 = $1.03 (his change)
Answer:
x = 9 and y = 1
Step-by-step explanation:
Here,
x = 10 - y and y = x - 8 is given
then, name the equation
x = 10 - y ...(1)
y = x - 8 ...(2)
Now, put the value of x in equation (2) we get
y = x - 8
y = (10 - y) - 8
y = 10 - y - 8
y + y = 10 - 8
2y = 2
y = 2÷2
y = 1
Here, we get the value of y = 1
Now, we put the value of y in equation (1) we get
x = 10 - y
x = 10 - (1)
x = 10 - 1
x = 9

x = 10 - y
9 = 10 - 1
9 = 9
Hence, LHS = RHS
