Answer 1

93) 2x-7+4x=x+3

6x-7=x+3

6x-x=3+7

5x=10

x=10/5

x=2

-15+8x+4=4-2x

-11+8x=4-2x

8x+2x=4+11

10x=15

x=15/10

x=3/2

96) 10x-1=10x+40-x-25

10x-1= 9x+15

10x-9x=15+1

x=16

1+12x=-4x-16+15

1+12x=-4x-1

12x+4x=-1-1

16x=-2

x=-2/16

x=-1/8

101) 3(5-x)-8=-5x+4

15-3x-8=-5x+4

7-3x=-5x+4

-3x+5x=4-7

2x=-3

x=-3/2

7x-2=5-2(x-1)

7x-2=5-2x+2

7x+2x=5+2+2

9x=9

x=9/9

x=1

105)5x-(x+3)-2(4-x)=2(8+x)-(3x-1)

5x-x-3-8+2x=16+2x-3x+1

6x-11=-x+17

6x+x=17+11

7x=28

x=28/7

x=3
