Simplify a - {5b - [a - (3b - 2c) + c - (a - 2b - c)]}.

-a - 6b + 4c
a - 6b + 4c
a - 10b + 4c
-a + 10b + 4c

a-6b+4c

Step-by-step explanation:

a-{5b-[a-(3b-2c)+c-(a-2b-c)]}

a-{5b-[a-1(3b-2c)+c-1(a-2b-c)]}

a-{5b-[a+(-3b+2c)+c+(-a+2b+c)]}

a-{5b-[a-3b+2c+c-a+2b+c]}

a-{5b-[-b+4c]}

a-{5b+[b-4c]}

a-{5b+b-4c}

a-{6b-4c}

a+{-6b+4c}

a-6b+4c

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.  

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
