Answer 2

Answer:

3x - 2y = 10

x + 3y = 7

Multiply the second equation by -3.

-3x -9y = -21

Add this to the first equation.

-11y = -11

Divide by -11.

y = 1

Plug this value for y into the first equation.

3x - 2(1) = 10

3x - 2 = 10

Add 2 to both sides of the equation.

3x = 12

Divide by 3.

x = 4.

So x = 4 and y = 1.
