Question

Subtract 5x-9 from x-4

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf{ - 4x + 5}}}}}`

Explanation:

`\sf{x - 4 - (5x - 9)}`

While subtracting, sign of each term of second expression changes

`\longrightarrow{ \sf{x - 4 - 5x + 9}}`

Collect like terms

`\longrightarrow{ \sf{x - 5x - 4 + 9}}`

`\longrightarrow{ \sf{ - 4x - 4 + 9}}`

The negative and positive integer are always subtracted but posses the sign of the bigger integer

`\longrightarrow{ \sf{ - 4x + 5}}`
