What is is being distributed in -3(x -4)?
-3
2x + 9y -10 + x - 8c
3x - 4 = 8
What are the four steps you need to follow to solve multistep equations?
1. Distribute
2. Combine like terms
3. Get rid of the addition/subtraction
4. Get rid of the multiplication/division
Simplify:
2x + 4 + 5x - 2
7x + 2
Solve:
x/5 + 2 = 5
x = 20
What would you do first to solve this?
3(3x + 4) - 9 = 27
Distribute the 3
Distribute:
4(3x - 2)
12x - 8
Simplify:
4x - 3 - 7x + 6
-3x + 3
-4y + 10 = 26
Solve:
3x + 9x - 4x + 9 = 33
Solve:
5(x - 2) = 10
4
Simplify:
3x - y + 12 - 10y + 4x
7x - 11y + 12
Solve:
3x - 5 = -7
-6
2x + 4(x - 2) = 40
x = 8
Using your own words, describe what "inverse operations" means
It means "doing the opposite" of the operation, i.e. inverse of division is multiplication... and so on
-2x(4 + 3) -3(x - 5)
Combine:
3x - 4y + x - 4x + 7y
3y
Solve:
9x - 4 = -15
x = -99
-5x + 2(x + 5) = -23
x = 11
