Solve the system of equations using substitution.<br> 3x + 7y = 19<br> -X + 8y = -27
Harman [31]

Answer:

x= 11

y= -2

Step-by-step explanation:

8y + 27 =x

3(8y+27) + 7y =19

24y + 81 + 7y =19

31y + 81 =19

<u>       -81    -81</u>

<u>31y</u> = <u>-62</u>

<u>31       31      </u>

y = -2

-x + 8(-2) = -27

-x - 16 = -27

<u>    +16    +16   </u>

-x = -11

x= 11
