Question

solve for c.
4c - 3 = 7 + 9c
c = \boxed{}

Explanation:

Step1: Subtract 4c from both sides

$4c - 3 - 4c = 7 + 9c - 4c$
Simplifies to: $-3 = 7 + 5c$

Step2: Subtract 7 from both sides

$-3 - 7 = 7 + 5c - 7$
Simplifies to: $-10 = 5c$

Step3: Divide both sides by 5

$\frac{-10}{5} = \frac{5c}{5}$
Simplifies to: $c = -2$

Answer:

-2
