A)11x-81=72x+102
B)11x-4=8x+14
C)1-(5-11x)=24-(10-8x)
D)(5-3x)-(-4x+6)=(8x+11)-(3x-6)
E)13x-(3x-2)-(5x+3-(x-1))=0
F)(14x-(2-2x))-(5x-3-(3-2x))=0

Answer 1

A. 11x -81 = 72x+102
11x-72x = 102+ 81
-61x = 183
X= 183/ -61
X= -3

B. 11x -4 = 8x + 14
11x -8x = 14 +4
3x = 18
X = 18/3
X= 6


C. 1-(5-11x) = 24 -(10-8x)
1-5+11x = 24 -10+8x
11x -8x = 24-10-1+5
3x = 18
X= 18/3
X= 6

D. (5-3x)-(-4x+6) = (8x+11)-(3x-6)

5-3x +4x-6= 8x+11-3x+6
-3x +4x-8x+ 3x = 11+ 6-5+6
-4x = 18
X= 18/-4
X= - 4.5

E. 13x-(3x-2)-(5x+3-(x-1)) = 0
13x -3x + 2 -(5x +3 -x +1)= 0
13x-3x+2-5x-3+x-1=0
13x-3x-5x+x= -2+3+1
6x= 2
X= 2/6

F. (14x-(2-2x))-(5x-3-(3-2x))= 0
(14x-2+2x)-(5x-3-3+2x)=0
14x-2+2x-5x+3+3-2x=0
14x+2x-5x-2x= 2-3-3
9x= -4
X=-4/9
