Step-by-step explanation:

First, let's add the two equations together to eliminate the variable y:

(7x - 3y) + (2x + 3y) = 15 + 12 7x - 3y + 2x + 3y = 27 9x = 27 x = 3

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

7(3) - 3y = 15 21 - 3y = 15 - 3y = 15 - 21 - 3y = - 6 y = 2

Therefore, the solution to the system of linear simultaneous equations is x = 3 and y = 2
