Question

Evaluate the expression for the given value of the variable 4|3x-1| - |9x+6| ; x=-5

Answer 1

Answer: 5

Explanation:

4|3x-1| - |9x+6| ; x=-5

Insert 5 into the x's

4|3(5)-1| - |9(5)+6|

Multiply the 5's

4|(15)-1| - |(45)+6|

Now add/subtract within the absolute values

4|14| - |51|

Get rid of the absolute vaules

4(14) - 51

Multiply 4(14) = 56

56 - 51 = 5
