Match column A and column B. Perform the indicated operations in column A and match the answer on column B.

Answer:

  1. d.
  2. b.
  3. h.
  4. j
  5. f.
  6. c.
  7. a.
  8. g.
  9. i
  10. e.

Step-by-step explanation:

1.

[tex]3x + 5x = 8x \\ \underline \green{8x}[/tex]

2.

[tex](2x - 3y) + ( - 5x + y) = - 3y - 2y \\ (2x - 3y) = 2x - 3y \\ 2x - 3y + ( - 5x + y) \\ - 3y + ( - 5x + y) = - 3y - 5x + y \\ 2x - 3y - 5x + y \\ 2x - 5x = - 3x \\ - 3x - 3y + y \\ - 3y + y = - 2y \\ \underline \green{ - 3y - 2y}[/tex]

3.

[tex](2xy + 3x - 2y) + (5xy - 4y) = 7xy + 3x - 6y \\ (2xy + 3x - 2y) = 2xy + 3x - 2y \\ 2xy + 3x - 2y + (5xy - 4y) \\ - 2y + (5xy - 4y) = - 2y + 5xy - 4y \\ 2xy + 3x - 2y + 5xy - 4y \\ 2xy + 5xy + 3x - 2y - 4y \\ 2xy + 5xy = 7xy \\ 7xy + 3x - 2y - 4y \\ - 2y - 4y = - 6y \\ \underline \green{7xy + 3x - 6y}[/tex]

4.

[tex](x ^{2} - {y}^{2} ) + (2 {x}^{2} + 3 {x}^{2} ) = 2 {y}^{2} + 3 {x}^{2} \: or \: 3 {x}^{2} + 2 {y}^{2} \\ ( {x}^{2} - {y}^{2} ) = {x}^{2} - {y}^{2} \\ {x}^{2} - {y}^{2} + (2 {x}^{2} + 3 {y}^{2} ) \\ - {y}^{2} + (2 {x}^{2} + 3 {y}^{2} ) = - {y}^{2} + 2 {x}^{2} + 3 {y}^{2} \\ {x}^{2} - {y}^{2} + 2 {x}^{2} + 3 {y}^{2} \\ 3 {y}^{2} - {y}^{2} + 2 {x}^{2} + {x}^{2} \\ 3 {y}^{2} - {y}^{2} = 2 {y}^{2} \\ 2 {y}^{2} + 2 {x}^{2} + {x}^{2} 2 {x}^{2} + {x}^{2} = 3 {x}^{2} \\ \underline \green{2 {y}^{2} + 3 {x}^{2} } \: or \: \underline \green{3 {x}^{2} + 2 {y}^{2} }[/tex]

5. Error Same Answer To The Question

6.

[tex]2y - y = y \\ \underline \green{y}[/tex]

7.

[tex](3y - 2) - ( - 2y + 5) = 5y - 7 \\ (3y - 2) = 3y - 2 \\ 3y - 2 - ( - 2y + 5) \\ - ( - 2y + 5) = 2y - 5 \\ 3y - 2 + 2y - 5 \\ - 2 - 5 = - 7 \\ 3y + 2y - 7 \\ 3 + 2y = 5y \\ \underline \green{5y - y}[/tex]

8.

[tex](5xy + 2x - 3y) - ( - 3xy - 5x) = 8xy + 7x - 3y \\ (5xy + 2x - 3y) = 5xy + 2x - 3y \\ 5xy + 2x - 3y - ( - 3xy - 5x) \\ - ( - 3xy - 5x) = 3xy + 5x \\ 5xy + 2x - 3y + 3xy + 5x \\ 5xy + 3xy + 2x + 5x - 3y \\ 5xy + 3xy = 8xy \\ 8xy + 2x + 5x - 3y \\ 2x + 5x = 7x \\ \underline \green{8xy + 7x - 3y}[/tex]

9.

[tex]( {x}^{2} + 3 {y}^{2} ) - (2 {x}^{2} - 5 {y}^{2} ) = - {x}^{2} + 8 {y}^{2} \: or \: 8 {y}^{2} - {x}^{2} \\ ( {x}^{2} + 3 {y}^{2} ) = {x}^{2} + 3 {y}^{2} \\ {x}^{2} + 3 {y}^{2} - (2 {x}^{2} - 5 {y}^{2} ) \\ - (2 {x}^{2} - 5 {y}^{2} ) = - 2 {x}^{2} + 5 {y}^{2} \\ {x}^{2} + 3 {y}^{2} - 2 {x}^{2} + 5 {y}^{2} \\ 5 {y}^{2} + 3 {y}^{2} - 2 {x}^{2} + {x}^{2} \\ 5 {y}^{2} + 3 {y}^{2} = 8{y}^{2} \\ 8{y}^{2} - 2 {x}^{2} + {x}^{2} \\ - 2 {x}^{2} + {x}^{2} = - {x}^{2} \\ \underline \green{ - {x}^{2} + 8 {y}^{2} } \: or \: \underline \green{8 {y}^{2} - {x}^{2} }[/tex]
