12x – 5y = -20<br> y = x +4

kari74 [83]

Answer:

x = $\frac{-40}{7}$ , y = -1.71

Step-by-step explanation:

sub y = x+4 in the first equation to get:

12 x - 5 (x+4) = -20

Simplify:

12 x - 5 x + 20 = -20

Further simplify:

7 x = - 40

Divie both sides by 7 to get:

x = $\frac{-40}{7}$

--> x = -5.7

Sub x = $\frac{-40}{7}$ in the second equation to get:

y = $\frac{-40}{7}$ + 4 = -1.71
