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.
8x β y = β9
4x β 3y = β22
4x β 3(β8x β 9) = β22
4x β 3(8x + 9) = β22
4(8x + 9) β 3y = β22
4(β8x β 9) β 3y = β22
