Gathering like terms together, this is equal to 5a + 3b + 7c.
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
12c + 2b
7c+4
16
No
c = 3
Its evaluation is: (4*5)+(7*3) = 41
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?
12a + 6b + 6c = 6(2a + b + c)
4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
