For this question, you can substitute in all the values for the variables. -c + b - a = -(5) + (-4.1) - (-2) = -5 - 4.1 + 2 = -9.1 + 2 = -7.1
Hope this helps! :)
− c + b − a = ? s u b s t i t u t e v a l u es : a = − 2 , b = − 4 , 1 c = 5 − c + b − a = − 5 + ( − 4 , 1 ) − ( − 2 ) = − 5 − 4 , 1 + 2 = − 9 , 1 + 2 = − 7 , 1
The evaluated expression − c + b − a with the given values results in − 7.1 . Substituting the values and simplifying step-by-step led to this conclusion. I hope this clarifies the evaluation for you!
