Its evaluation is: (4*5)+(7*3) = 41
No
7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2
12a + 6b + 6c = 6(2a + b + c)
1 and 3/4
12c + 2b
c = 3
No
7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2
12a + 6b + 6c = 6(2a + b + c)
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?

Get two slaves. Give one equation to each slave. Say, "Go!"
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.

12c + 2b
4a+3b can not be algebraically simplified. It can be evaluated if you assign values to a and b.
