Well I got this:
2c+7=9+6-7c+2c
2c+7=15-9c
11c+7=15 (add 9c)
11c=8 ( Subtract 7)
11---11 ( Divide 11)
C=0.72
-3.5. 2c would turn into -1.5 and seven wold turn to 3.5. add the two together and you get 2. 2+6=8 and you have your answer.
Gathering like terms together, this is equal to 5a + 3b + 7c.
Oh, dude, that's like super easy. So, 7c plus c is basically just adding up the number of c's, which gives you 8c. It's like math, but with letters instead of numbers. So yeah, 7c plus c equals 8c. Math made fun, right?
It equals 10c+2 because you have to combine like terms when you use variables. So since there is a 7c and a 3c you add those because it says plus add you end up with 10c+2 because you are still adding the 2.
Need your help for answer
7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2
7c+4
-3.5. 2c would turn into -1.5 and seven wold turn to 3.5. add the two together and you get 2. 2+6=8 and you have your answer.
4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
16
2c-10
c = 3
Its evaluation is: (4*5)+(7*3) = 41
No
12a + 6b + 6c = 6(2a + b + c)
Gathering like terms together, this is equal to 5a + 3b + 7c.
