The two equations given in the question are
y = - 3x
And
y = 6x - 9
Let us now substitute the value of y from the first equation to the second equation, we get
y = 6x - 9
- 3x = 6x - 9
-3x - 6x = - 9
- 9x = - 9
Multiplying both sides of the equation by -1 we get
9x = 9
x = 9/9
= 1
Now let us put the value of x in the first equation, we get
y = - 3x
= - (3 * 1)
= - 3
Answer:
The number of hours did Sarah practice more than Leilani is
hours .
Step-by-step explanation:
Given as :
The time for which Leilani practiced piano =
hours
The time for which Sarah practiced piano =
hours
Let the number of hours did Sarah practice more than Leilani = T hours
<u>Now, According to question</u>
The number of hours did Sarah practice more than Leilani =
hours -
hours
Or, T =
hours
Or, T =
hours
So,The number of hours did Sarah practice more than Leilani = T =
hours
Hence, The number of hours did Sarah practice more than Leilani is
hours . Answer
