Suppose 3x+4y=52 and 5x+y= 30. What is the value of 8x-2y
1 answer:
Answer:
12
Step-by-step explanation: If you made x, 4 and y, 5 then all equations would make sense if you change the letters to numbers.
IF
(3*4)+(4*10)=52
and
(5*4)+10=30
then
<h2>
(8*4)-2*10=<u><em>
12</em></u></h2><h2 />

Answer:
B. -2
Step-by-step explanation:
2(x - 4) + 3x - x2
