Answer:

# color(green)(x = -24#

Explanation:

# 2/3x+9=-7#

Trasnposing #9# to the right hand side, we get

#2/3x = -7 - 9#

#2/3x = - 16#

Multiplying both sides of the equation with 3, we get

#2/cancel(3)x times cancel(3) = - 16 times 3#

#2x = -48#

Dividing both sides by 2, we get

#(cancel(2)x) / cancel(2) = -48/2#

# color(green)(x = -24#
