Question

5(x + 3) - (9x - 4)

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf - 4x + 19}}}}`

Explanation:

`\sf{5(x + 3) - (9x - 4)}`

Distribute 5 through the parentheses

⇒
`\sf{5x + 15 - (9x - 4)}`

When there is a ( - ) in front of an expression in parentheses, change the sign of each term in the expression. Also, remove the parentheses

⇒
`\sf{5x + 15 - 9x + 4}`

Collect like terms

⇒
`\sf{5x - 9x + 15 + 4}`

⇒
`\sf{ - 4x + 15 + 4}`

Add the numbers : 15 and 4

⇒
`\sf{ - 4x + 19}`

Hope I helped!
