Answer:
x = 7
y = 2
Step-by-step explanation:
In the above question, we are given 2 equations which are simultaneous. To solve this equation, we have to find the values of x and y
x + 3y = 13 ........ Equation 1
x - y = 5...........Equation 2
From Equation 2,
x = 5 + y
Substitute 5 + y for x in Equation 1
x + 3y = 13 ........ Equation 1
5 + y + 3y = 13
5 + 4y = 13
4y = 13 - 5
4y = 8
y = 8/4
y = 2
Since y = 2, substitute , 2 for y in Equation 2
x - y = 5...........Equation 2
x - 2 = 5
x = 5 + 2
x = 7
Therefore, x = 7 and y = 2
Answer:
>
Step-by-step explanation:
17/5 is 8.5 but √70 is 8.3 something that for 17/2>√70
Our function is:
Now, if 
is a factor of 
then 
must satisfy the equation:
So, 
Putting
We get,
So, the value of 'a' for the given expression is 1281.
3w-13w=-20
Combine like terms
-10w=-20
divide both sides by -10
w=2
