Solve the system by the method of your choice. identify systems with no solution and systems with infinitely many solutions, using set notation to express their solution sets. x + y = -8 x - y = 14 a. {( 3, -11)} b. {( 3, 11)} c. {(x, y) | x + y = -8}

The answer is B. because if u add 11to -8, it becomes 3 andthe other side will already be 3. so 3=3.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
