1-4 complex solving strategies

1-4 complex solving strategies

Remember the goal

• Our goal is to get the letter (variable)by itself

• We use opposite operations to remove terms from the same side of the equation as the variable

• Entire terms are added or subtracted

• Coefficients of our variable are divided.

• Today, we will deal with a variable on both sides of the equal sign.

Using opposite operations

• 2x=-x+9 We can add x to both sides of the equal sign

• 3x=9 then solve by dividing by 3

• 2x - 12 = 24-2x first add 2x to both sides of the equal sign

• 4x-12=24 now, add 12 to both sides of the equal sign

• 4x=36 Then solve by dividing by 4

Multiple Choice

Solve for f:
f - 4 = 6f + 26

• f = -5
• f = 5
• f = 6
• f = -6

how do you feel about solving with variables on both sides of the equal sign?

• I am ready for the next level of difficulty

• I can do this but would like another example problem

• I need another teacher led example

• Help Me

Let's put everything you know into 1 problem

• What if we have x on both sides with distribution and combining like terms?

• LET'S GO!!!

Multiple Choice

Solve: 4(w + 3) = 2(5w + 6)

• w = 6

• w = 0

• w = 0.5

• w = 1

Multiple Choice

• - 4
• 3
• 0
• 4
