Solve using either elimination or substitution.If the system has either no solution of an infinite number of solutions,state so:
7x-2y=24
5x+4y=28

Please show us the work you've done to try to solve this system. When we can see your work, we will have a better idea of how to help you.

Hints:

Substitution Method — (1) solve one of the equations for y, and (2) substitute the result for y in the other equation.

(Doing this gives you an equation that contains only the variable x, for which you can solve.)

Elimination Method — (1) multiply the first equation by 2, and (2) add the resulting equation to the second equation.

(Doing this gives you an equation that contains only the variable x, for which you can solve.)

Thanks for the help in explaining this process to me. It helped get this done.

You're welcome.

I reviewed your posts at this site. You've shown some work on a couple requests for help, but mostly not.

I see that three people have asked you to show what you've tried or explain why you're stuck.

Please make an attempt to do this, in future requests for help. If you don't tell us where you're at, we really have no way to determine where to begin helping you.
