Question

(x + y = 5 (x-y=3 Помогыте пж

Answer 1

x+y = 5            y= 5-x

подставляем в другое

x- (5-x) =3

x-5+x=3

2x=8

x=4

подставляем икс в 1 выражение

4+y=5

y=1

Answer 2

Sure, I can help you with that system of equations. Let's solve it step by step.

The given system of equations is:

1. x + y = 5
2. x - y = 3

To solve this system, we can use the method of elimination. Let's add the two equations together to eliminate the variable "y":

(x + y) + (x - y) = 5 + 3

Simplifying the equation: 2x = 8

Dividing both sides by 2: x = 4

Now that we have the value of x, we can substitute it back into one of the original equations to solve for y. Let's use equation 1):

4 + y = 5

Subtracting 4 from both sides: y = 1

So the solution to the system of equations is x = 4 and y = 1.

Therefore, the values of x and y that satisfy both equations are x = 4 and y = 1.
