Answer:

Step-by-step explanation:
Given

Required
Rewrite to show y-intercept
We have: 
Subtract x from both sides

Divide both sides by z

<em>The y intercet is: </em>
<em></em>
Y-4X =3 ; 2x-3y=21
Y= 3+ 4x
2x -3( 3+4x)= 21
2x- 9- 12x= 21
-10x -9= 21
-10x -9+9= 21+9
-10x = 30
X= 30/-10= -3
Y= 3+4x = 3+ 4* (-3)= 3-12= -9
Answer:
x = 12/11, -32/11
