Answer:
The solution is x = 3 and y = 21
Step-by-step explanation:
Here, we want to solve the system of linear equations, simultaneously
Since we have 2 y
Then we can equate both and that gives;
4x + 9 = 2x + 15
4x-2x = 15-9
2x = 6
x = 6/2
x = 3
To get y, we simply substitute x into any of the equation
That will be;
y = 2(3) + 15
y = 6 + 15
y = 21
