# How do you solve the following system?:  7y=4- 2x , 3x + y = -1

$\left(- \frac{11}{19} , \frac{14}{19}\right) \in m a t h \boldsymbol{Q \times Q}$

#### Explanation:

$y = - 1 - 3 x$

$7 \left(- 1 - 3 x\right) = 4 - 2 x$

$- 7 - 4 = - 2 x + 21 x$

$- \frac{11}{19} = x$

$y = - 1 - 3 \left(- \frac{11}{19}\right) = \frac{- 19 + 33}{19}$
