When graphed, 'greater than or equal to' and 'less than or equal to' is always graphed with
2x + 11 = 73
a closed (colored in) circle
2x - 6 = 20
-11
(x/2) - 6 = 88
add or subtract the constant (single number)
flip the sign
multiply or divide the coefficient
The first step in a 2-step equation is always
2x + 11 = 73
a closed (colored in) circle
2x - 6 = 20
-11
(x/2) - 6 = 88
add or subtract the constant (single number)
flip the sign
multiply or divide the coefficient
When solving an inequality, anytime you multiply or divide by a negative number, you must
