Can someone help me to figure out this equation. I dont remember how to do this with the outside brackets

- math -
**Reiny**, Monday, November 23, 2009 at 2:12pmstart with the innermost brackets and work outwards

2{[5(c-4)+15]-[3(5c-3)+1]}

= 2{[5c-20+15]-[15c-9+1]}

= 2{[5c-5]-[15c-8]}

= 2{5c-5-15c+8]}

= 2{-10c+3]}

= -20c + 6
