Answer:
21
Step-by-step explanation:
8x+y, when x=2 and y=5,
then 8*2+5. Because the 2 is right next to the 8, it isn't '82', but '8*2'
According to PEMDAS, multiplication is done first, so
8*2= 16,
16+5, which is 16+5= 21
Just search up the name of your worksheet online and then at the end of the name/title,lesson and chapter/unit type in "answer key"
Answer:
Step-by-step explanation:
figure it out kid
<span>A) 5x + 7y = 3
B) 2x + 3y = 1
Multiplying Equation B by -2.5
</span><span>B) -5x -7.5y = -2.5 Then adding this to Equation A)
A) 5x + 7y = 3</span>
-.5y = .5
y = -1
Since
<span>2x + 3y = 1 then
2x -3 = 1
then x = 2
</span>
and surely you know what that is
