I need help with these two problems. I need to have all of the steps shown for full credit and I get lost along the way.
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.
Multiply 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 <).
