What is the solution of the system of equations? y = 3x + 7 and y = x - 9
Solution:
It is given that,
y = 3x + 7 and y = x - 9
Let us assume,
y = 3x + 7 … [equation 1]
Also assume,
y = x - 9 … [equation 2]
Consider equation 1 and substitute the value of equation 2 in equation 1,
y = 3x + 7
x - 9 = 3x + 7
By transposing we get,
3x - x = - 9 - 7
2x = -16
x = -16/2
x = -8
Now, substitute the value of x in equation 2 we get,
y = x - 9
y = - 8 - 9
y = - 17
Therefore, the solution of the system of equations is x = - 8, y = - 17.
What is the solution of the system of equations? y = 3x + 7 and y = x – 9
Summary:
The solution of the system of equations y = 3x + 7 and y = x - 9 is x = - 8, y = - 17.
