Question 651780

{{{98-4b= -11b}}}...move {{{-11b}}} to the left and {{{98}}} to the right side of equal sign (recall that sign changes in this case)

{{{11b-4b= -98}}}

{{{7b= -98}}}

{{{b= -98/7}}}

{{{highlight(b= -14)}}}

we can check result by plugging {{{highlight(b= -14)}}} in {{{98-4b= -11b}}}

{{{98-4(-14)= -11(-14)}}}...recall:when multiplying two negative numbers, the product will be positive number 

{{{98+56= 154}}}

{{{154= 154}}}...true; so, {{{highlight(b= -14)}}} is a solution for {{{98-4b= -11b}}}
