6x - 2y = 10

4x + 3y = 12

solve the system by elimination.

solve inequality

-2(2x-6)-4x>or equal to 3x-10 + 9

It's at this point in our lessons I keep losing my previous knowledge. I think I need time to let the previous knowledge sink in before moving on. However, that isn't acceptable.

Thanks for your help.

**PsyDAG**, Friday, June 10, 2011 at 3:46pmMultiply the top equation by 3 and the bottom equation by 2. Then add the two equations. This will elimination the y term.

-2(2x-6)-4x ≥ 3x-10 + 9

-4x+12-4x ≥ 3x-10 + 9

Combine like terms. It works just like an equation, except that multiplying/dividing by a negative value reverses the carat (e.g., > ot <).
