Since you are failing, i will not give you the answer directly so you can learn, and not just copy the answer down. First, think about what the variable means. They have an open spot in the equation and they give you what to fill in. since x=-3, multiply 5 by -3. You do this because in the equation it says x5 which is equal to x times 5. Then substitute the y, or -5 to have 6(-5)+(-3)5
