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.]
