Question

Subtract the sum 5b- 4c+a and 2c - 3b - 4a from the sum of (a + 2b -3c) and 2c - 3b - 4a

Answer 1

first we will add the two equations then subtract,

Step-by-step explanation:

adding 5b- 4c+a and 2c - 3b - 4a gives,

2b-2c-3a ---(1)

adding (a + 2b -3c) and 2c - 3b - 4a gives,

-b-c-3a ---(2)

subtracting (1) and (2)

3b-c, will be our answer
