#-20#

There are 2 terms. Work out an answer for each term first and then add or subtract the answers in the last step.

#3color(red)((4-7)) - 11 " start in the bracket"#

=#3color(red)((-3)) -11#

=#-9 - 11#

=#-20#

Multiplying out using the distributive law gives the same result.

#3(4-7) -11#

=#12-21 -11#

=#-20#
