Question

Subtract the following using horizontal method
i.)2x from-5x
ii.)-5a from 18a

Answer 1

i)-7x ii)23a

Explanation:

i)U well get -5x-2x, after solving, u well get -7x since all is negetive. ii)U well get 18a-(-5a) which u well get 18a+5a whict is equal to 23a

Answer 2

`\huge{ \boxed{ \text{ i. \: \ - 7x}}}`

`\huge{ \boxed{ \text{ii. \: 23a}}}`

☄ 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.

`\longrightarrow{ \sf{ - 5x - (2x)}}`

`\longrightarrow{ \sf{ - 5x - 2x}}`

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

`\longrightarrow{ \boxed{\sf{ - 7x}}}`

Likewise , Let's do next too:

• -5a from 18 a

`\dashrightarrow{ \sf{ 18a - ( - 5a)}}`

Remember :
`\sf{( - ) * ( - ) = ( + )}`

`\dashrightarrow{ \sf{ 18a + 5a}}`

`\dashrightarrow{ \boxed{ \sf{ 23a}}}`

And we're done!

Hope I helped!

Have a wonderful time ツ
