Answer:

$x=-6$

Step-by-step explanation:

So we have the equation:

$-34=7(x+8)+8x$

First, distribute the 7 into the (x+8) and simplify:

$-34=7(x)+7(8)+8x\\-34=7x+56+8x$

Combine the like terms 7x and 8x by adding them together:

$-34=56+15x$

Subtract 56 from both sides to isolate the x:

$-34-56=15x+56-56\\15x=-90$

Divide both sides by 15 to get x:

$x=-90/15=-6$

y = 159 $
For the second month we have:
y = 150 * (1.06) ^ 2
y = 168.54 $
