<PRE><B>Question 1129216</B>
 If 9 is subtracted from two-thirds of a number, the result is 7.
Just write an equation for exactly what it says
{{{2/3}}}x - 9 = 7
add 9 to both sides
{{{2/3}}}x = 7 + 9
{{{2/3}}}x = 16
get rid of the annoying fraction, multiply both sides by 3, cancels the 3
2x = 3(16)
2x = 48
x = 48/2
x = 24
:
:
Check solution in original equation, x=24
{{{2/3}}}(24) - 9 = 7
16 - 9 = 7
