Answer :
Answer:
Y = 14
Step-by-step explanation:
1/2(-9 + y) = 2.5
1/2 * -9 = -4.5
1/2 * y = 0.5y
-4.5 + 0.5y = 2.5
+4.5 +4.5
0.5y = 7
/0.5 /0.5
y = 14
Answer:
[tex] \frac{1}{2} ( - 9 + y) = 2.5 \\ - 4.5 + 0.5y = 2.5 \\ minus \: - 45 \: both \: sides \: of \: the \: equation \\ \frac{0.5y}{0.5} = - \frac{ 7}{0.5} \\ y = 14[/tex]
