Step-by-step explanation: When you add the -3 and + 3 they equal zero and that single y has an imaginary 1 in front of it so 1y+4y=5y. And -2 +-38 is -40. :)

Solve 8x + c = k for x.

Scrat [10]

Answer:

$x = \frac{k -c}{8}$

Step-by-step explanation:

$8x + c = k\\\\8x + c-c = k -c \ \ \ \ \ \ \ \ \ [\ subtract \ c \ from \ both \ sides \ ]\\\\8x = k - c\\\\\frac{8x}{8} = \frac{k-c}{8} \ \ \ \ \ [ \ divide \ both \ sides\ by\ 8 \ ]\\\\x = \frac{k-c}{8}$
