400 reduced by 3 times my age is 163. what is his age?

I would represent his age as "x"

The equation is:

3x = 400 - 163.

= 3x = 237

Divide by 3.

3x = 237
 /3      /3

 x = 237/3

x = 79 * 3/3

x = 79.

So his age is 79.

All about the same size in the city the game was

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
