Answer 1

a)-2-x+5=-2x+3x-10x
-X+10X+2X-3X=2-5
-8X=-3 (-1)
X=3/8

b)-1-3x-7x+4-2=0
-3X-7X=1-4+2
-10X=-1 (-1)
X=1/10

c)0=-3x+1-x-7x+10x-15
3X+X+7X-10X=-15+1
11X-10X=-14
X=-14

Answer 2

a)
-2-x+5=-2x+3x-10x
-x+10x+2x-3x = 2-5
8x = -3
x = -3/8

b)
-1-3x-7x+4-2=0
-3x-7x=1-4+2
-10x = -1
x = 1/10

c)
0=-3x+1-x-7x+10x-15
3x+x+7x-10x=-15+1
11x-10x=-14
x = -14
