$62 times 8% = $4.96
$62+$4.96= $66.96
$66.96+$15= $81.96
Multiply the first equation by 2:-
2y + 4.6 = 0.90x
2y - 0.90x = -4.6
second equation is
-2y - 4.2x = -7.8
Adding:-
-5.1x = -12.4
x = 2.4
-2y = -7.8 + 4.2(2.4) = 2.3
x = -1.2
Answer x = 2.4 and y = -1.2
Its choice A
This would be 19/2 if u fract dec be like 19.2 not sure if it is right but hipe it helps lol
17-2x that should be right
