Question

X+y=3202x+y=470x=?y=?​

Answer 1

Ответ:

x=150. y=170

Пошаговое объяснение:

x=320-y

2*(320-y) + y= 470

640-2y+y=470

-y=470-640

y=170

x=320-170=150

Answer 2

To solve for x and y in the system of equations:

1. x + y = 320
2. 2x + y = 470

You can use either the substitution method or the elimination method. I'll use the elimination method here:

First, subtract equation 1 from equation 2 to eliminate the y variable:

(2x + y) - (x + y) = 470 - 320

This simplifies to:

x = 150

Now that you've found the value of x, you can substitute it into either equation 1 or 2 to find the value of y. I'll use equation 1:

x + y = 320 150 + y = 320

Subtract 150 from both sides:

y = 320 - 150 y = 170

So, the solutions to the system of equations are:

x = 150 y = 170
