Answer 2

To find : value of expression $2a + 3b - c$

Given : $a = 3 , b = -4 , c = -2$

Solution :  

• As per given data we are given values $a = 3 , b = -4 , c = -2$

• To find the value of expression we substitute the given values in it .
• By performing arithmetic operations like addition and subtraction we find the value of expression .  
• $2a + 3b -c$

       $=2 ( 3 ) + 3 ( -4 ) - (-2 ) \\= 6 -12 + 2 \\= -6 + 2 \\ = -4$

Hence , the value of expression is $- 4$  .
