By the Elimination method, you are left with 8x = 16 because -8 and 8 are what are called AdditiveInverses,meaning they result in 0⃣; x = 2, plug 2⃣back into both equations, and you will see that y = 1, making the solution above.
“Product” means the answer you get from multiplying two or more numbers together. * Tip: A negative number times another negative number equals a positive.
