Answer:


\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!

Best regards!!
