Question

5a - [2b-{4C -(6a -2b+3c-2a)}]
there is a bar --------- over 2b+3c-2a ​

Answer 1

Step-by-step explanation:

Answer:

a + c

Step-by-step explanation:

5a −[2b −{4c −(6a − 2b + 3c −2a)}]

= 5a −[2b −{4c −(4a − 2b +3c)}]

= 5a −[2b −{4c - 4a +2b - 3c}]

= 5a −[2b −{c - 4a +2b }]

= 5a −[2b - c + 4a - 2b ]

= 5a - [4a - c]

= 5a - 4a + c

= a + c
