#m=-12#

The equation is:

#4-m/2=10#

We will multiply the whole equation by #2#:

#4*2-m/2*2=10*2#

#8-m=20#

Now, subtracting #8# from both sides:

#8-8-m=20-8#

#-m=12#

#m=-12#

#m=-12#

#color(blue)(4-m/2=10#

Subtract #4# both sides

#rarrcancel4-m/2cancel(-4)=10-4#

#rarr-m/2=6#

Multiply both sides by #2#

#rarr-m/cancel(2)*cancel2=6*2#

#rarr-m=12#

#color(green)(rArrm=-12#

Check

#4-(-12)/2=10#

#4+12/2=10#

#4+6=10#

#10=10#

Correct!
