I have no idea what to do here.

Solve the following system of equations for \(c\):

\(\begin{align*} a - b &= 2(c + d) \\ b &= a - 2 \\ d &= c + 8 \end{align*}\)

#1**+1 **

a - b = 2 (c+d) but b = a-2 sub that in

a - ( a-2) = 2 ( c+d)

2 = 2 ( c+d)

1 = c+d now d = c+8 sub that in

1 = c + c+8

1 = 2c + 8

-7 = 2c

c = - 7/2
