Collecting Like Terms


Today in class we learned how to solve like term questions. Terms that have the same variable parts are like terms.

e.g 1. 3x + 7x = 40
Add 3+7 = 10
10x / 10 = 40 / 10
x = 4
3(4) + 7(4) = 40

When solving like terms, you always want 1 variable and 1 integer term on each side.

e.g 2. 4x + 6 - 2x - 9 = 9
4x - 2x + 6 - 9 = 9
2x / 2 - 3 = 9 + 3 / 2
+3
x = 12 / 2
x = 6


And for those of you who missed class today, we created a parent quiz, which your parent/parents will take at . We will be heading down to the lab to type it into our power point presentations. In total, there will be 11 slides for math, that will show things on exponents, 1 step algebra, and its rules. They are: Isolate the variable, cancel the integer, balance, cancel what is attached to the variable, balance, and substitute to check.

  • Nice post Ashley. You should use colour to show the different aspects of the equation solving. You can edit your post and put the colour in.

    Great post. keep Blogging
