Choose an expression that is equivalent to the following
6n + 2(3 - 5n)
n + 6
6 - 4n
16n + 6
Choose the first step in solving the following equation.
-3y - 12 = 14
add 3 from both sides
add 12 to both sides
subtract 12 from both sides
0.1( x - 20 ) > 2
x > 40
x < 40
x > 220
-12x > 36
x > -3
x > 48
x < -3
- 3( 4 - 2x) = 6
x = 1
x = -3
x = 3
When solving an inequality, what are the main things that are different from solving equations.
Draw the line
Use inverse operations to solve.
Bring down the inequality symbol and FLIP the symbol when you multiply or divide by a negative.
