Answer:
1)
Isolate for the variable m
-13 = 5 + 20m -2m
-13 = 5 + 18 m
-18 = 18 m
m = -18/18
m = -1
2) same thing
11 + 8r = -r +29
8r + r = 29 - 11
9r = 18
r = 18 / 9
r = 2
3) same thing
4x +6 +3 = 17
4x = 17 - 6 - 3
4x = 17 - 9
4x = 8
x = 8 /4
x =2
4) Same thing
-8(-8x - 6) = -6x -22
64x +48 = -6x -22
64x +6x = -22 -48
70x = -70
x= -70/70
x = -1

Answer:
Given - AB = X + 5
BC = 2(x - 3)
= 2x - 6

AB = BC
x +5 = 2x - 6
x- 2x = (-6)-5
-x = (-11)
x = 11
Value of X = 11
