Answer:
x + y = 5
3x + 3y = 15
Step-by-step explanation:
let x represent apple and y represent orange
Hence x + y = 5
and 3x + 3y = 15
Solving both equations simutaneously
From first equation, x = 5-y
Substitute x=5-y into the second equation
3(5-y)+3y = 15
y= 0
x = 5-0 = 5
Answer:
the system : 9x-3y =21
2x+3y = 12
Step-by-step explanation:
hello :
an system of equations has the same solutions as the system below
the system 3x-y=7
2x+3y=12
for exempl : 3×(3x-y)=3×7
2x+3y)=12
means :
9x-3y =21
2x+3y = 12
Since this is a permutation, it would be 5!(factorial)
so 5x4x3x2x1
Let me just say that that's an amazing picture
ok
standard form is ax+by=c where a,b, and c are integers and a is usualy positive
18y=24x-9
minus 18y both sides
0=24x-18y-9
add 9 to both sides
9=24x-18y
24x-18y=9
divide both sides by 3
8x-6y=3 is standard form
