how many side and angles does a trapezoid angle, hexagon, and pentagon have?

solve each equation:

13 + y = -3, 3y + 8=3, y over 3= -9

need help with + & - rules for adding whole numbers, decimals, fractions and integers ( do not understand) and rule for multiplying + & -

Google the fist question

hint --- hex means 6 and pent means five

13 + y = -3

-13 = -13 add

-----------------

13-13 + y = -16

y = -16

=============================

3y + 8=3

-8 = -8 add

---------------

3 y + 0 = -5

y = -5/3

=============================

y over 3= -9

3 (y/3) = 3 (-9)

y = -18
