An equation is shown

4c+2c=4c+11/2

what value of 2c makes the equation true.

c = 11/4

Step-by-step explanation:

One way of doing this is to let 2c = x.  Then our equation becomes

2x + x = 2x + 11/2, or x = 11/2.

But 11/2 = 2c.  Thus, c = 11/4

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
