Presentation Transcript
step number 1
Step Number 1
  • Look at the Equation

2(x + 5) + 3x = -5(x + 4) + 15x

step number 2
Step Number 2
  • Apply the Distributive Property if it is in the equation.

Original: 2(x + 5) + 3x = -5(x + 4) + 15x

2x +10 + 3x = -5x – 20 + 15x

step number 3
Step Number 3
  • Combine Like Terms on EACH side of the equals sign

Combining Like Terms is like collecting apples and oranges……only put terms together that look EXACTLY alike!

Last Step: 2x + 10 + 3x = -5x – 20 + 15x

Combining: 5x + 10 = 10x - 20

step number 4
Step Number 4

Add or Subtract

(Goal: Get variables on one side of the equals sign and all whole numbers on the other side)

5x + 10 = 10x – 20

- 10 - 10

5x = 10x – 30

-10x -10x

-5x = -30

step number 5
Step Number 5
  • Multiply or Divide

(Goal: To get the variable alone with only a 1 in front of the variable)

-5x = -30

-5 -5

( Anything divided by itself is 1)

step number 6
Step Number 6
  • Find the solution to the equation

-5/ -5 = 1x and -30/-5 = 6 so,

My solution is : x = 6

step number 7
Step Number 7
  • Check your answer

2(x + 5) + 3x = -5(x + 4) + 15x

2(6 + 5) + 3(6) = -5(6 + 4) + 15(6)
