if x - y = -10,2x + 3y = 15what is the value of y?	Choose the correct choice
A) 8
B) 6
C) 7
D) 6.5
E) 5
solution   Rearranged I--&gt; y = x + 10   Substituted into II---&gt; 2x + 3(x + 10) = 15   we get x = -3   Solve for Y: 2(-3) + 3(y) = 15   y = 7   Answer is 7
<result>C</result>
if x - y = -10,2x + 3y = 15what is the value of y?
