    Solve for x in the first equation 3x+8=2 after subtracting 8 and dividing both sides by 3, getting x=-6/3=-2. Now substitute -2 for x in the second equation. Then solve for y. Is that enough help?

    Fine, when you substitute the -2 for x in the second equation you get: 7(-2)+3y=1 or -14+3y=1 Now solve for y.

    X was solved in my first response. X is -2 Now we will solve for Y. Using the second equation substitute (-2) for the x value. This will get you 7(-2)+3y=1 or -14+3y=1 Add 14 to both sides getting 3y=15. Now solve for y by dividing both sides by 3 getting y=5. Now you have the value of both x and y.
