Bosnian, I really could use your help on one other problem. I have been working on it and what helps is that you show the steps. Solve using the elimination

Question

method. 5x - 7y = -16, 2x + 8y = 26

Thanks so much for your help

Answer 1

multiply the first equation by 8, the second by 7
40x-56y=-128
14x+56y=182
then add the equations
54x=54
x=1

Now, elimination for solving x
multiply the first equation by 2, and the second by 5
10x-14y=-32
10x+40y=130
subtract the second equation from the first
-54y=-162
y=3
