Answer

Problem

Simplify the expression
\$ (-f+1/2g-e) + (1/3f-5g-4/5e) \$

Step

After eleminating the brackets we get

\$ -f + 1/2g - e + 1/3f - 5g - 4/5e\$

Step

Adding like terms together

\$ (-f + 1/3f) + (1/2g - 5g) + (-e - 4/5e)\$

Step

Taking variables common

\$ (-1 + 1/3) f + (1/2 - 5) g + (-1 - 4/5) e \$

Step

Taking LCM as 2,3,5

\$((-3 + 1)/3)f + ((1 - 10)/2)g + ((-5 - 4)/5)e \$

Step

After simplification we get

\$ -2/3f - 9/2g - 9/5e \$
