Answer:
1.3c - 10
Step-by-step explanation:
( 5.2c - 7.35 ) + ( - 3.9c + 2.65 )
= ( 5.2c - 7.35 ) - ( 3.9c + 2.65 )
= 5.2c - 7.35 - 3.9c + 2.65
= 5.2c - 3.9c - 7.35 + 2.65
= 1.3c - 10
1. make the + and - sign become only one, which will be - as when + and -, it will be -
2. take out the values from their brackets
3. arrange the values so like terms with the like terms, and in this case c and c, constant with constant
4. solve the equation and you will get the answer
