The question is which answer does show the standard form of the equation: 7-3 (x-y) = - 5x+2. To see that let's transform our equation into standard form. Standard form of a linear equation is: ax+by=c. So our equation is: 7-3x+3y=-5x+2. Now we put the unknowns on the left and the numbers on the right: - 3x+5x+3y=2-7 and we get 2x+3y=-5. And we see that the correct answer is C.
