Answer:
Step-by-step explanation:
By putting the value of y (4x - 12) from equation (2) in equation (1)
We get: 2x + (4x - 12) = 18
6x - 12 = 18
6x = 18 + 12
6x = 30
x = 30/6
Value of x is: x = 5
Now, by putting x = 5 in equation (2)
We get: y = 4(5) - 12
y = 20 - 12
Value of y is: y = 8
So, x = 5 and y = 8
