Solution (5):

Simplifying the expression.

  • (8x + 1) + (-x + 7)
  • => 8x + 1 - x + 7
  • => 7x + 8

Solution (6):

Simplifying the expression.

  • (8x - 3) - (3x + 1)
  • => (8x - 3) + (-3x - 1)
  • => 8x - 3 - 3x - 1
  • => 5x - 4

Solution (7):

Simplifying the expression.

  • (2x + 7) + (4x - 10)
  • => 2x + 7 + 4x - 10
  • => 6x - 3

Solution (8):

Simplifying the expression.

  • (-7x + 2) - (3x - 3)
  • => (-7x + 2) - 3x + 3
  • => -7x + 2 - 3x + 3
  • => -10x + 5

Let's solve ~

First ~

[tex]\qquad \sf  \dashrightarrow \: (8x + 1) + ( - x + 7)[/tex]

[tex]\qquad \sf  \dashrightarrow \: 8x + 1 - x + 7[/tex]

[tex]\qquad \sf  \dashrightarrow \: 8x - x + 1 + 7[/tex]

[tex]\qquad \sf  \dashrightarrow \: 7x + 8[/tex]

Second ~

[tex]\qquad \sf  \dashrightarrow \: (8x - 3) - (3 x + 1)[/tex]

[tex]\qquad \sf  \dashrightarrow \: 8x - 3 - 3x - 1[/tex]

[tex]\qquad \sf  \dashrightarrow \: 8x - 3x - 3 - 1[/tex]

[tex]\qquad \sf  \dashrightarrow \: 5x - 4[/tex]

Third ~

[tex]\qquad \sf  \dashrightarrow \: (2x + 7) + (4x - 10)[/tex]

[tex]\qquad \sf  \dashrightarrow \: 2x + 7 + 4x - 10[/tex]

[tex]\qquad \sf  \dashrightarrow \: 2x + 4x + 7 - 10[/tex]

[tex]\qquad \sf  \dashrightarrow \: 6x - 3[/tex]

Fourth ~

[tex]\qquad \sf  \dashrightarrow \: (- 7x + 2) - (3x - 3)[/tex]

[tex]\qquad \sf  \dashrightarrow \: - 7x + 2 - 3x + 3[/tex]

[tex]\qquad \sf  \dashrightarrow \: - 7x - 3x + 2 + 3[/tex]

[tex]\qquad \sf  \dashrightarrow \: - 10x + 5[/tex]
