hi, can anyone figure out the solution to 4x + 3y = 17 and y = 3/4x - 19/4 and if possible can you show me exactly how you figure it out step by step? thanks for any help

ah, in case anyone was in the process of writing a reply to this, i just realised that the answer must be x = 5 and y = -1. sorry for any inconvenience
$\displaystyle \left\{\begin{array}{ll}4x+3y=17\\y=\frac{3}{4}x-\frac{19}{4}\end{array}\right.$ Replace y in the first equation: $\displaystyle 4x+3\left(\frac{3}{4}x-\frac{19}{4}\right)=17$ $\displaystyle 25x=125\Rightarrow x=5$ Now find y.
