Solve the equation 6+(c+8)=136-(c+8)-131+7(t+2)=854(A+4)-9(A-4)=3711=7-(1-y)3+7(p-10)= -38-(5-3p)20+5(3-5A)=-5(A-6)+5

Let's solve the next equation:

$6+(c+8)=13$

We need to find the value for c, this value is correct when we replaced it with a number and the equality equation becomes true.

First, subtract both sides by 6

$6-6+(c+8)=13-6$ $c+8=7$

Now, subtract both sides by 8

$c+8-8=7-8$ $c=-1$

Replacing the c value to verify:

$6+(-1+8)=13$ $6+7=13$

The c value is correct.
