Best ResponseYou've already chosen the best response.0One of my good ways would be to actually plug in the numbers

Best ResponseYou've already chosen the best response.0I will teach that to you. Do you know what the absolute value symbols mean?

Best ResponseYou've already chosen the best response.0that whats inside it is positive ?

Best ResponseYou've already chosen the best response.0Yes or, in other words, the distance from that number and 0 (that's why it's positive).

Best ResponseYou've already chosen the best response.0So what will happen to the negative numbers once you plug them inside of the absolute value?

Best ResponseYou've already chosen the best response.0If we first plug in 3 for x. \[33+7\] First, we need to work with the numbers inside of the parenthesis. what is 3 + 7?

Best ResponseYou've already chosen the best response.0sorry not the parenthesis, i meant the absolute value symbols.

Best ResponseYou've already chosen the best response.0x: −3x + 7 = −12 divide both sides by 3 x + 7 = 4 now the left side is positive but the x + 7 can be negative or positive so we have x + 7 = 4 or x + 7 = 4 solve these 2 equations

Best ResponseYou've already chosen the best response.03 + 7 = 4 absolute value would just be 4
