Answer

Problem

Simplify the expression
\$ (4a+4b+1/c) + (-4a+7b-2/c) \$

Step

After eleminating the brackets we get

\$ 4a + 4b + 1/c - 4a + 7b - 2/c \$

Step

Adding like terms together

\$ (4a - 4a) + (4b + 7b) + (1/c - 2/c) \$

Step

Taking variables common

\$ (4 - 4) a + (4 + 7) b + (1/c - 2/c) \$

Step

Taking LCM as C

\$ 0 + 11b + ((1-2)/c) \$

Step

After simplification we get

\$ 11b - 1/c \$
