Which first step for solving the given system using substitution results in an equation without fractions? negative 9 x plus 4 y is equal to 10 negative 9 x plus 3 y is equal to 3

Solve for y in the second equation, −9x + 3y = 3. Adding 9x gives 3y = 3 + 9x, and dividing by 3 gives y = 1 + 3x, with no fractions. Solving for y in the first equation or for x in either equation introduces a fractional coefficient.
