Answer:
x = -12
y = 11
Step-by-step explanation:
i used substitution and let 'x' = 10 - 2y
3(10 - 2y) + 4y = 8
30 - 6y + 4y = 8
30 -2y = 8
-2y = -22
y = 11
x + 2(11) = 10
x + 22 = 10
x = -12
Answer:
$98.75
Step-by-step explanation:
50×75÷100 = 37.5 + 50 = 87.5
87.5 × 30 ÷ 100 = 26.5
87.5 - 26.5 = 61.25
87.5 + 61.25 = 148.75
148.75 - 50 = 98.75
