Question

What is the value of x in the solution to this system of equations?

Answer 1

Answer:

x = 11

Step-by-step explanation:

$x-3y=-7$

$5x=-2y+67$

=> $x=\frac{1}{5}(-2y+67)$

=> $x=-\frac{2}{5}y+\frac{67}{5}$

=> $-\frac{2}{5}y+\frac{67}{5}-3y=-7$

=> $-\frac{17}{5}y+\frac{67}{5} =-7$

=> $\frac{-17}{5}y=-\frac{102}{5}$

=> y = 6

=> $x=-\frac{2}{5} .6+\frac{67}{5}$

=> x = 11
