Question 310618
You have two equations in two unknowns.

t + w = 495....This is your first equation.

t/10 = w....This is your second equations.

After solving for w, I got 45.

But we need to find t.

So, replace w with 45 in EITHER equation above.

I will use t + w = 495 to find t.

t + w = 495

t + 45 = 495

t = 495 - 45

t = 450
