Question

Solve by elimination:

-6x+3y=-4
-20x+10y=20

i know the answer is no solution, but i need to know why. ​

Answer 1

Ok, there's no solution because of the like term grouping

Explanation:

For eg;2w+3x+4w will be equal to

6w+3x which is a like term grouping. So only if there are like terms, there will be a solution.
