Question 24318
3/4(b+8)=15
You need to also distribute the 3/4 to 8;
{{{3/4}}}(b)+{{{3/4}}}(8)=15
{{{3/4}}}b+{{{24/4}}}=15
{{{3/4}}}b+6=15
{{{3/4}}}b=9
Now multiply each side by the reciprical of {{{3/4}}}, which is {{{4/3}}};
{{{3/4}}}b{{{4/3}}}=(9){{{4/3}}}
b={{{36/3}}}
b=12
hope you understand
=)
