Thank you so much for helping!
Haii isn't 2x-6-12+3x
Equals to 5x-6-12
Equals to 5x-(-6)
Equals to 5x+6
Equals to 5x-6-12
Equals to 5x-(-6)
Equals to 5x+6
Step 2 to step 3 ....
5x -6 -12
Is not 5x -(-6)... this is plus and minus working
In positive (+ve) and negative(-ve) value... for additional and subtraction
-ve can be explained as owe money
+ve can be explained as pay money
So here, owe 6 dollars then owe 12 dollars again, total owe 18 dollars.
Same for other like -6 + 8
owe 6 dollars, pay 8 dollars, extra +2 dollars.
5x -6 -12
Is not 5x -(-6)... this is plus and minus working
In positive (+ve) and negative(-ve) value... for additional and subtraction
-ve can be explained as owe money
+ve can be explained as pay money
So here, owe 6 dollars then owe 12 dollars again, total owe 18 dollars.
Same for other like -6 + 8
owe 6 dollars, pay 8 dollars, extra +2 dollars.
Ohhh ohk thxx
