If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation.
12x β y = β4
4x β 3y = β6
answer
4x β 3(β12x β 4) = β6
4(12x + 4) β 3y = β6
4(β12x β 4) β 3y = β6
4x β 3(12x + 4) = β6
