Slack variable is a variable that is added to a constraint to switch form an inequality to equatlity equation.

Mathematical signs would help.

You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14

You add 12... r + (-12) = 19 r + (-12) + 12 = 19 + 12 r = 31

Without an equality sign the given expression can't be considered to be an equation.

the answer is -11+x=26 -11+x+11=26+11 -11and +11 will be cut therefore x=37

76= -43 + X add 43 to both sides 76 + 43 = -43 + 43 + x 119 = x

18+y=32 y=14

there is nothing being added or multiplied to it, and it is on its own side of the equal sign
