Question

find the sum using of monomials using clounm method -2a+3b,5a+2b-c and -a -b -c

Answer 1

Step-by-step explanation:

$( - 2a + 3b) + (5a + 2b - c) + ( - a - b - c)$

$- 2a + 3b + 5a + 2b - c - a - b - c$

$( - 2a + 5a - a) + (3b + 2b - b) + ( - c - c)$

$(2a) + (4b) + ( - 2c)$

$2(a + 2b - c)$
