To find the value of |2x-3y| given that x = 0.5 and y = -0.7, you need to substitute the values of x and y into the expression |2x-3y|.
Start with the expression |2x-3y|. Replace x with the value of 0.5 and y with -0.7:
|2(0.5) - 3(-0.7)|
Now, simplify the expression inside the absolute value brackets:
|1 - (-2.1)|
Next, simplify the subtraction inside the absolute value brackets:
|1 + 2.1|
Finally, add the values inside the absolute value brackets:
|3.1|
The value of |2x-3y| when x = 0.5 and y = -0.7 is 3.1.
