Answer:
x= 9
y=-12.5
Step-by-step explanation:
3x+2y = 2×2
2x+2y =-7×3
6x+4y =4
- 6×+6y =-21
-2y =25
y=-12,5
2x+2(-12,5)= -7
2x+-25= -7
2x= -7+25
2x/2=18/2
x= 9
The Answer is A because 7 is in the $ side and 35 in the boxes.
$7 / 35 boxes.
price of one message = 1.35 ÷ 9
1.35 ÷ 9 = 0.15
0.15 • 118 = ( 3 ÷ 20 ) • 118
118 • 3 = 354
354 ÷ 20 = 177 ÷ 10 = $17.7 to send 118 messages
