Remember order of operations:
1.) Do everything in the parenthesis first.
2.) Do exponents/logarithms (doesn't seem to apply here)
3.) Do multiplication/division
4.) Do addition/subtraction
Once you've done that, simplify by combining like terms:
For example: 12a + 1b + 15a + 3 + 13a - 2b can be rewritten as:
12a + 15a + 13a + 1b - 2b + 3
40a - 1b + 3
that's as far as that can be simplified.

You need to re-enter it so the whole problem shows up. But basically if there's a minus sign outside parentheses, change it to plus and change the sign of each thing inside the parentheses. Then add every like term inside the brackets. Then multiply everything by the number outside the brackets.

Previous posts are correct, we cannot help until the whole problem is posted. Study "order of operations" on the net. Briefly, inside the parentheses is done before outside, then add and subtract before you multiply and divide.

25-[10a-(11b-7)-(16b-14)+(8b+6-3)]
=25-(10a-11b+7-16b+14+8b+3)
=25-(10a-27b+24+8b)
=25-(10a-19b+24)
=1-10a+19b
