Answer:

Step-by-step explanation:

We have a system with the value of y given in one equation as 3x-5.  If y=3x-5 then we can sub that in for y in the other equation.  So instead of the second equation being

6x + 3y = 15, it becomes

6x + 3(3x - 5) = 15

Solving for x:

6x + 9x - 15 = 15 and

15x = 30 so

x = 2
