How do you solve #3(x+8)=12#?

1 Answer

Jul 9, 2016

#x = -4#

Explanation:

There are 2 ways to approach this equation:

Using the distributive law,:

#3(x +8) = 12#
#3x + 24 = 12#
#3x = 12-24#
#3x = -12#
#x = (-12)/3#
#x = 4#

Or by isolating the bracket by dividing both sides by 3 first:

#(3(x +8))/3 = 12/3#

#x + 8 = 4#
#x = 4-8#
#x = -4#
