- Oh! So, they both have the same variables...
- ...And if the number is positive then we add an addition symbol
- SIMPLIFYING EQUATION/COMBINING LIKE TERMS
- 12..7x + y -11.9y -4x12.7x-4x= 8.7xy-11.9y= -10.9y
- And then we simplified the equation.
- and if its a negative, we add a subtract symbol.
- Right------>Charlie
- ...Meaning, we need to combine them
- <------Kendall
- h
- Meaning, we multiply 2 with 7 and 3a...
- So now we need to simplify our new equation...3a-14-6a
- and the difference is -3a. So our final equation is -3a-14
- 2x7= 142-3a= 6a
- 3a - 2(7 - 3a)
- 3a - 14 -6a3a-6a=-3a-3a-14
- ------>Charlie
- OK. So we need to distribute 2 into 7 and 3a
- Since 3a and 6a have the same variable we need to subract them
- The product is 14 for 2x7 and 6a for 2-3a.
- n
- After getting out new equation of -x+4-5x-15
- <------Kendall
- So first, we distribute the negative into the first parentheses.
- -(x - 4)-5(x + 3)
- -x + 4 -5x - 15
- -6x-11
- ------->Charlie
- And then we combine the like variables to get the final answer of -6x-11
- And then we distribute the -5 into the second parentheses.
- nm
- Ok, so we distribute .5 into the first parenthesis and -2 into the 2nd
- So, it would be 2x+6x= 8x and -3-14= 17.
- 0.5(4x - 6) -2 (7-3x)
- 2x - 3 -14 +6x
- 8x-17
- Having our final equation to be 8x-17
- After distributing, we combine the like terms
- 8+6=14-6n+5n= h
- Now we start to combine the like varibles. 8+6= 14 and -6n+5n= -n
- Like the other problems, we need to distribute 2/3 into the first set of parenthesis
- 2/3 (12-9n) +5n-(-6)
- 8-6n+5n+6
- 14-n
- -n
- And then we have to distribute negative into -6 which equals 6
- a negitive times a negitive equals a positive
- And the final answer is 14-n
- (4x + 5) - (6x - 2)4x + 5 - 6x + 2-2x + 7a) -2x + 3 b) 2x + 3 c) 10x - 7 d) -2x + 7
- Right, then we have to solve all the right terms
- D!!!
- First we have to take out the parenthesis
- Then we got -2x + 7 which is....
