Answer 2

Let's break this down one by one and solve for x and a:

67343-x=6309/9

First, let's simplify the right-hand side of the equation:

6309/9 = 701

Now we can substitute this value in the equation:

67343 - x = 701

We can solve for x by subtracting 67343 from both sides:

-x = -66642

And then we can solve for x by multiplying both sides by -1:

x = 66642

x/420 = 13256 - 3314*4

We can start by simplifying the right-hand side:

13256 - 3314*4 = -8012

Now we can substitute this value in the equation:

x/420 = -8012

We can solve for x by multiplying both sides by 420:

x = -8012*420

x = -3365040

(1512-504*3)+a=12437/27

First, let's simplify the left-hand side of the equation:

1512 - 504*3 = 0

Now we can substitute this value in the equation:

0 + a = 461

We can solve for a by subtracting 0 from both sides:

a = 461

Therefore, the solutions to the system of equations are:

x = 66642 a = 461
