2х+у=11 3х-у=9

To solve this system of equations, we can use the method of substitution or elimination.

Let's solve it using the method of substitution.

From the first equation, we can rearrange it to solve for y: 2x + y = 11 y = 11 - 2x

Now substitute this expression for y in the second equation: 3x - (11 - 2x) = 9 3x - 11 + 2x = 9 5x - 11 = 9 5x = 20 x = 4

Now substitute the value of x into the first equation to solve for y: 2(4) + y = 11 8 + y = 11 y = 11 - 8 y = 3

Therefore, the solution to the system of equations is x = 4 and y = 3.
