7x+4y=43

Can't be factored, but you can solve for x or y.

7x + 4y = 43

7x = 43 - 4y

x = (43 - 4y)/7

7x + 4y = 43

4y = 43 - 7x

y = (43-7x)/4

This equation is "Prime."

7x+4y=43 43*7=301

-43 -43

7x+4y-43=0

There is nothing in this

equation that can be multiplied to get 301 and added to get 4, therefore the problem is prime.

7x+4y=43

-4y=-4

7x=39

7 =7

x=5.5

It's not factorizable...my ti-89 calculator said so (it can factors things)

yes....it cannot factorise...the question is not complete...there must be another formula...x+2y=9....or somethin' like that
