If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the second equation is substituted into the first equation.
2x β 3y = β29
x + 4y = 13
2(4y + 13) β 3y = β29
2(β4y + 13) β 3y = β29
2x β 3(4y + 13) = β29
2x β 3(β4y + 13) = β29
