Answer 3

It seems you have a system of equations with two variables, 'a' and 'x'. To solve for 'a' and 'x', we can break it down into two separate equations and solve for each variable.

1. 450 + a = 920 - 40x

First, let's isolate 'a' on one side of the equation:

a = 920 - 40x - 450

Now, simplify the right side:

a = 470 - 40x

2. 920 - 40x - 340 = 180 + 20

Let's simplify this equation:

580 - 40x = 180 + 20

Combine like terms on both sides:

580 - 40x = 200

Now, subtract 580 from both sides to isolate the term with 'x':

-40x = 200 - 580

-40x = -380

Finally, divide both sides by -40 to solve for 'x':

x = -380 / -40 x = 9.5

Now that we have found the value of 'x', we can substitute it back into the first equation to solve for 'a':

a = 470 - 40x a = 470 - 40(9.5) a = 470 - 380 a = 90

So, the solution to the system of equations is: a = 90 x = 9.5
