Answer:
x = 9 , y = - 3
Step-by-step explanation:
(1)
8.88 = 4.44(x - 7) ← divide both sides by 4.44
2 = x - 7 ( add 7 to both sides )
9 = x
(2)
5(y + [tex]\frac{2}{5}[/tex] ) = - 13 ← distribute parenthesis by 5
5y + 2 = - 13 ( subtract 2 from both sides )
5y = - 15 ( divide both sides by 5 )
y = - 3
