Actually Welcome to the concept of Linear Equations

After solving all the Equations we get as,

I have solved the Above four equations, 1.) and no. 2.) is the horizontally adjacent to no. 1.) , hope you get it.

1.) 2x = 14 ===> x = 14/2 ===> x = 7

2.) X - 5 = 20 , X = 20+5 ===> X = 25

3.) 4 + (x +6) = 10 ==> 10 + x = 10 ==> x = 0

4.) 7(x-12) = 21 ===> x-12 = 3 ===> x = 15

9.) -8x -8 = 160 ===> -8x = 168 ===> x = -21

10.) -8k -5 = -133 ==> -8k = -128 ==> K = 16

11.) 0 = -12n+12 ===> -12n=-12 hence, n = 1

12.) -7+n/2=4 ==> -7-4 = -n/2 ==> -11 =-n/2 ==> -n=-22 ==> n = 22

13.) 7*3= n-7 ==> 21=n-7 ==> n = 28

14.) 4+m/10 = 2 ==> 4+m = 20 ==> m = 20-4 ==> m=16
