10-1.75 = 0.65x
9.25 =0.65x
9.25/0.65=x
then simplify or find the exact solution
Answer:
x=5, y=8
Step-by-step explanation:
Since both equations equal y, we can set them equal
y = x + 3
y = 2x - 2
x+3 = 2x-2
Subtract x from each side
x-x+3 = 2x-x-2
3 = x-2
Add 2 to each side
3+2= x-2+2
5 =x
Now we need to find y
y =x+3
y=5+3
y=8
yes 831 is divisible by 3
One way I know this is because when adding all the digits in the number you get 12 which is divisible by 3
Also if you do divide 831 ÷ 3 it would equal 277
