4x row 3 box 2 that’s the only one I know

Answer 2

Step-by-step explanation:

Start filling in from the bottom, left to right

Row 2 from bottom:

• -2x + 3
• 3 + (-5) = -2
• -5 + 7y = 7y - 5
• 7y + 1

Row 3 from bottom:

• 2x + (-2x) + 3 = 3
• -2x + 3 + (-2) = -2x + 1
• -2 + 7y - 5 = 7y - 7

Row 4 from bottom:

• 3 + (-2x) + 1 = -2x + 4
• 7y - 7 - 5 + 15y =  22y - 12

Row 5 from bottom:

• -2x + 4 -2x - 6 + 7y = -4x + 7y - 2
• -2x - 6 + 7y + 22y - 12 = -2x + 29y - 18

Top row:

• -4x + 7y - 2 - 2x + 29y - 18 = -6x + 36y - 20
