Question

10 + 5Y = X
40 + 10Y = X

Answer 1

(x,y)=(-20,-6)

Explanation:

Answer 2

X = -50

Y = -30

Explanation:

To find the value of Y and X, we can solve a system of equations. One way to do this is by substitution.

From the first equation:

10 + 5Y = X

We can substitute the value of X from the second equation:

10 + 5Y = 40 + 10Y

Then, we can subtract 10Y from both sides:

10 = 40 + Y

Finally, we can subtract 10 from both sides:

Y = -30

Now that we have the value of Y, we can substitute it back into either equation to find the value of X:

X = 10 + 5Y

X = 10 + 5(-30)

X = -50

So the solution is:

X = -50

Y = -30
