times= multiply 
sum= addition 
is= equal sign 
x= a number 
4 times x plus 2/3 equals 16/3.
4x + 2/3= 16/3
subtract 2/3 from both sides
4x= 14/3
divide both sides by 4
x= 14/3 ÷ 4
to divide fractions, multiply by reciprocal/inverse of 4 
x= 14/3 * 1/4
multiply numerators (top); multiply denominators (bottom) 
x= (14*1)/(3*4)
x= 14/12
simplify by 2
x= 7/6
ANSWER: The number in simplest form is 7/6.
