Question 184115
use the same rules you use for arithmetic.
{{{1-3(5b-2)=4-(7b+3)}}}  first use distribution
{{{1 - 15b + 6 = 4 - 7b - 3}}} collect like terms
{{{7 - 15b = 1 - 7b}}}  now isolate the terms with variables
{{{7 -1 = 15b - 7b}}}  simplify
{{{6 = 8b}}} now solve for b
{{{6/8 =  b}}}  simplify
{{{3/4 = b }}}

Check your answer by plugging 3/4 in for b and verifying that boths sides are the same
