Please help me thank you

Answer 1

For the system of equations x + y = 5 and 2x - y = 3:

1. Add both equations: 3x = 8, divide by 3 to get x = 8/3.

2. Substitute x back into either equation: (8/3) + y = 5, so y = 7/3.

Therefore, the solution is x = 8/3 and y = 7/3.

For the system of equations:

x + y=5

2x-y=3

We can solve this system of equations using elimination. Here's how:

1. Add the top and bottom equations together:

3x = 8

2. Divide both sides by 3:

x =
`(8)/(3)`

3. Substitute this value of x back into either of the original equations to solve for y:

`((8)/(3)) + y = 5`

`y = (7)/(3)`

Therefore, the solution to the system of equations is x = 8/3 and y = 7/3.
