# How do you solve the system of equations 8x + 3y = 93 and 4x + 3y = 69?

Apr 30, 2018

$y = 15$
$x = 6$

#### Explanation:

$8 x + 3 y = 93$ --- (1)
$4 x + 3 y = 69$ --- (2)

(1) minus (2)
$4 x = 24$
$x = 6$ --- (3)

Sub (3) into (2)
$4 \left(6\right) + 3 y = 69$
$24 + 3 y = 69$
$3 y = 45$
$y = 15$
