1. 2x-10=5x-1

subtract 2x from both sides:

2x-10-2x=5x-1-2x

-10=3x-1

Add 1 to both sides:

-10+1=3x-1+1

-9=3x

Divide both sides by 3:

-9/3=3x/3

-3=x

x=-3

2. -4x-6=-3x-15

Add 4x to both sides:

-4x-6+4x=-3x-15+4x

-6=x-15

Add 15 to both sides:

-6+15=x-15+15

9=x

x=9

3. 15x-10=22x+39

Subtract 15x from both sides:

15x-10-15x=22x+39-15x

-10=7x+39

Subtract 39 from both sides:

-10-39=7x+39-39

-49=7x

Divide both sides by 7:

-49/7=7x/7

-7=x

x=-7

4. 16x-32=8x+16

Subtract 8x from both sides:

16x-32-8x=8x+16-8x

8x-32=16

Add 32 to both sides:

8x-32+32=16+32

8x=48

Divide both sides by 8:

8x/8=48/8

x=6
