2x + 9y -10 + x - 8c
3x - 4 = 8
3(3x + 4) - 9 = 27
What does the word combine mean?
to put together
Solve:
3x + 9x - 4x + 9 = 33
x= 3
-x(3 + 4)
-4y + 10 = 26
What are the 5 steps you need to follow to solve multistep equations?
1. Distribute
2. Combine like terms
3. Move the variable
4. Add/subtract the constant
5. Multiply/divide the coefficient
Combine the like terms :
3x - y +12 - 10y + 4x
7x -11y + 12
Which operation would you do first, when trying to solve this for x?
x + 7 - 5 = 10
What is the goal of solving a multistep equation?
To get the variable by itself
-2x(4 + 3) -3(x - 5)
3x - 4y + x -4x + 7y
Solve:
2x - 5 = 3
x = 4
Solve:
9n - 6 = 5n + 18
Solve:
-3x - 4(4x - 8) = 3(-8x -1)
x = -7
