☄ Question : Subtract the following using horizontal method :

  • i. 2x from -5x
  • -5a from -18a

✎ Step - by - step Explanation :

  • 2x from -5x

In horizontal method , terms are arranged in same row and put sign for subtraction and remove the brackets and then simplify.

[tex] \longrightarrow{ \sf{ - 5x - (2x)}}[/tex]

[tex] \longrightarrow{ \sf{ - 5x - 2x}}[/tex]

Like terms can be added or subtracted. Only coefficients of like terms can be added or subtracted.

[tex] \longrightarrow{ \boxed{\sf{ - 7x}}}[/tex]

Likewise , Let's do next too:

  • -5a from 18 a

[tex] \dashrightarrow{ \sf{ 18a - ( - 5a)}}[/tex]

Remember : [tex] \sf{( - ) \times ( - ) = ( + )}[/tex]

[tex] \dashrightarrow{ \sf{ 18a + 5a}}[/tex]

[tex] \dashrightarrow{ \boxed{ \sf{ 23a}}}[/tex]

And we're done!

Hope I helped!

Have a wonderful time ツ
