Answer:

120

Explanation:

We start with the equation:


(1)/(3)x-(3)/(8)x -(7)/(24)x =-40

We need to set the fractions into equal denominations so we can sum them all together:


(8)/(24)x-(9)/(24)x -(7)/(24)x =-40\\

Now sum the fractions:


(8-9-7)/(24)x=-40\\\\ (-8)/(24)x=-40

Multiple both sides by 24 to eliminate denominator on left side of equation:


-8x=-960

Divide both sides by -8 to get the value of x:


x=120
