Answer: 15x-14y=22
3x+5y=7
2.5x-y=17
42x+0.4y=15
Step-by-step explanation:
The standard linear equation of two variables x and y is given by :-
Ax +By = C , where A is a positive integers, and B, and C are integers.
Therefore, from the given options the linear equations that are in standard form are
15x-14y=22
3x+5y=7
2.5x-y=17
42x+0.4y=15
[-2x+8y=14 is not in standard form ∵ -2 is a negative integer.]

Yes the greatest common factor of odd numbers will always be odd
We know, 1 oz = 28349.5 mg
so, 7 oz = 198447
So, it would be: 198447 * 2%
= 198447 * 0.02
= 3968.24 mg
In short, Your Answer would be 3968.24 mg
Hope this helps!
Rewrite it as
3r-1=8
3r=8+1
3r=9
R= 3
