1-2x+5=4x-3

1+5-2x=4x-3

6-2x=4x-3

Move 6 to the other side

Sign changes from +6 to -6

6-6-2x=4x-3-6

-2x=4x-9

Move 4x to the other side

Sign changes from +4x to -4x

-2x-4x=4x-4x-9

-2x-4x=-9

-6x=-9

Divide both sides by -6

-6/-6=-9/-6

x=9/6

reduce the fraction by dividing by 3

9/3=3

6/3=2

Answer: x=3/2 or x=1 1/2

\huge\boxed{x=(3)/(2)}

We need to isolate
x.


1-2x+5=4x-3

Rearrange the terms a little bit.
-2x+1+5=4x-3

Add the like terms.
-2x+6=4x-3

Subtract
4x from both sides.
-2x-4x+6=-3

Subtract
6 from both sides.
-2x-4x=-3-6

Combine the like terms.
-6x=-9

Divide both sides by
-6.
x=(-9)/(-6)

Simplify.
x=\boxed{(3)/(2)}
