Write the expresion in simplest form<br> (-11/2x+30)-2(-11/4x-5/2)

qwelly [4]

The simplified expression of (-11/2x+30)-2(-11/4x-5/2) is 35

<h3>How to simplify the expression?</h3>

The expression is given as:

(-11/2x+30)-2(-11/4x-5/2)

Expand the bracket

-11/2x + 30 + 11/2x + 5

Collect the like terms

11/2x -11/2x + 30 + 5

Evaluate the like terms

Hence, the simplified expression of (-11/2x+30)-2(-11/4x-5/2) is 35
