We are given that:

  • a = 5
  • b = -4
  • c = -3

Given the expression:


\displaystyle \large{2a - 6b + 3c}

Evaluate the expression by substituing the given values in.


\displaystyle \large{2(5)- 6( - 4)+ 3( - 3)} \\ \displaystyle \large{10- ( - 24)+ ( - 9)}

Simplify the expression.

  • Negative × Negative = Positive
  • Negative × Positive = Negative


\displaystyle \large{10 + 24 - 9} \\ \displaystyle \large{34- 9} \\ \displaystyle \large \boxed {25}

Therefore, the value of the expression is 25.
