Answer:
Step-by-step explanation:
A) 3x-1=4x+8-x
3x-4x-(-x)-1=8
3x-4x+x=8-1
-x+x=8-1
0=7
no solution
Answer: No Solution
---------------------------
B) -10+5x=7x-4
-10+5x-7x=-4
-10-2x=-4
2x=-10-(-4)
2x=-10+4
2x=-6
x=-6/2
x=-3
Answer: x=-3
----------------------
C) 28-6x=30-3x
28-6x-(-3x)=30
28-6x+3x=30
28-3x=30
3x=28-30
3x=-2
x=-2/3
Answer: x=-2/3
----------------------
D) 4x-1=9x-1-5x
4x-9x-(-5x)=-1+1
-5x-(-5x)=0
-5x+5x=0
0=0
Infinitely many solutions.
