Question 254707
We start with the expression as
{{{8a=15(8a-(a+(8a-5)))+2}}}
step 1 - take away (_) around 8a-5 to get
{{{8a=15(8a-(a+8a-5))+2}}}
combine like terms a + 8a - 5 to get
{{{8a=15(8a-(9a-5))+2}}}
step 3 - distribute the (-) into 9a-5 to get
{{{8a=15(8a-9a+5)+2}}}
step 4 - combine like terms 8a - 9a + 5 to get
{{{8a=15(-1a+5)+2}}}
step 5 - now distribute the 15 to get
{{{8a=-15a+75+2}}}
step 6 - combine like terms -15a+75 + 2 to get
{{{8a=-15a+77}}}
step 7 - add 15a to both sides to get
{{{23a = 77}}}
divide by 23 to get
a = 77/23.
