Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

3x + y = -2

5x - y = -10

Step 2: Solve for x

Eliminate y

Add 2 equations together:                     8x = -12Divide 8 on both sides:                           x = -12/8Simplify fraction:                                      x = -3/2

Step 3: Solve for y

Define original equation:                    3x + y = -2Substitute in x:                                     3(-3/2) + y = -2Multiply:                                                -9/2 + y = -2Add 9/2 on both sides:                        y = 5/2

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )
