Answer:
$10.71
Step-by-step explanation:

y × 35 = 3.75 × 100
35y = 375
35y ÷ 35 = 375 ÷ 35

y = 10.7142857143
10.7142857143 round to 10.71

Answer:
x = -9/4
Step-by-step explanation:
−2(x + 1/4) + 1 = 5
Subtract 2 from both sides.
−2(x + 1/4) = 4
Divide both sides by -2.
x + 1/4 = -2
Subtract 1/4 from both sides.
x = -2 1/4
x = -9/4
Y-2x=-3.5
x-2y=-14
then multiply the first term by 2
2y-4x=-7
x-2y=-14
then sum them
-3x=-21
x=-7
y=3.5
