Is this a system of equations?
2X + 5Y = 4
X + 5Y = 7
solve for X using bottom equation
X = 5Y - 7
insert into top equation
2(5Y - 7) + 5Y = 4
distribute
10Y - 14 + 5Y = 4
solve for Y
15Y = 18
Y = 18/15 = 6/5
use bottom equation to find X
X +5(6/5) = 7
X = 1
check with bottom equation
1 + 5(6/5) = 7
7 = 7
not true for top equation
( sorry, I forgot what happens then-resubmit question )
