Answer:
See below
Step-by-step explanation:
13x + 5 + 17x - 4.5 + x
NOTE: You can only add/subtract LIKE terms . Here we have variable terms in x (13x , 17x and x) and 2 constants ( 5 and 4.5).
Sarah's next line is
18x + 17x - 4.5 + x
This is incorrect . It looks like she added 13x + 5 and got 18x!! Which is of course wrong because they are NOT LIKE terms. 5 is a constant and 13x is a variable term in x.
The third line is correct:-
35x - 4.5 + x.
She has added the 2 variables 17x and 18x.
Fourth line is 30.5x + x. She's at it again - Trying to subtract 4.5 from 35x .
Last line 31.5x
She has added the 2 terms in x correctly, but the final answer is wrong of course due to the earlier errors.
okay so basically i like to switch it around, you dont have to though.
1 Simplify 6x+4x-66x+4x−6 to 10x-610x−6
10x-6=24+9x1
2 Add 66 to both sides
10x=24+9x+610x=24+9x+6
3: Simplify 24+9x+624+9x+6 to 9x+309x+30
10x=9x+3010x=9x+30
4 Subtract 9x9x from both sides
10x-9x=3010x−9x=30
5 Simplify 10x-9x10x−9x to xx
x=30
The answer will be - 17/12
