Please help answer with solutions- thank you

A. Use the three methods of solving nonlinear equations to find the solutions of these systems of nonlinear equations. Elimination substitution Graphing 1 . 5 x 2 + y 2 - 100 method method 7 y = 3 4 X 2 . 5 - x 2 - 3 x ty = 0 - 12 * 2 - 3 x ty = 0 5 4 2 - 3 x 2 = 12 Y = - 3 x 4 . 5 X 2 + 3 4 2 = 63 3 4 - X = 3 5. 5 - 9 x + 34 = 12 x 2 +y = 2 6 .5 2 x 2 - xy ty ? = 8 x 2 = y 5 124 2 - 18y- 54= 0 7. 12 42 - 34 - 9=0 B. Solve the systems of nonlinear equations, using any method of your choice. 1.5 2 X2 + y 2 = 18 2 . $ 2 x 2 + 3 y 2 +3x - 12y - 42=0 xy = 41 x +3y = 0
