Question 55053
5[2-(2x-4)]=2(5-3x)

Start by working within the [ ] 
5[-2x-2]=2(5-3x)
Distribute the 5 across the [ ]
{{{ -10x-10=2(5-3x) }}}
On the right side, distribute the 2
{{{ -10x-10=10-6x }}}
Since the -10x is the smaller x value, move it by adding 10x to both sides
{{{ -10x+10x-10=10-6x+10x }}}
Combine like terms
{{{ -10=10+4x }}}
Sumbtract 10 from both sides
{{{ -10-10 = 10+4x-10 }}}
Combine like terms
{{{ -20 = 4x }}}
Divide by 4
{{{ -5 = x }}}
