Answer:
AC = 12x + 20
Step-by-step explanation:
Combine the terms:
AB + BC = AC
AB = 8x + 2
BC = 4x + 18
Plug in the corresponding terms to the corresponding variables:
(8x + 2) + (4x + 18) = AC
AC = 8x + 4x + 18 + 2
AC = 12x + 20
12x + 20 is your answer for AC.

Step-by-step explanation:
X+2y=5
X-3y=7
To write a determinant we take the coefficient of the variables
To get first row we take the coefficients of x and y from the equation x+2y = 5
x or 1x are same
1x+2y = 5
The coefficient of x is 1 and coefficient of y is 2
So first row is 1 , 2
We do the same for second row
To get second row we take the coefficients of x and y from the equation x-3y = 7
1x - 3y = 7
The coefficient of x is 1 and coefficient of y is -3
So second row is 1, -3
