Answer

Problem

Simplify the expression
\$ (3a+5b+5/c^2) + (-2a+7b-1/c^2) \$

Step

After eleminating the brackets we get

\$ 3a + 5b + 5/c^2 - 2a + 7b - 1/c^2 \$

Step

Adding like terms together

\$ (3a - 2a) + (5b + 7b) + (5/c^2 - 1/c^2) \$

Step

After simplification

\$ a + 12b + (5 - 1)/c^2 \$

Step

After simplification we get

\$ a + 12b + 4/c^2 \$
