Answer:
y-intercept = 3
Step-by-step explanation:
3x + 4y = 12
4y = -3x + 12
4y/4 = -3/4x + 12/4
y = -3/4x + 3
Answer:
The values of x and y to the given equation are x=3 and y=-1
The solution to the given equation is (3,-1)
Step-by-step explanation:
Given equations are 

To solve given equations by using elimination method :
Mutliply the equation (2) into 2 we get

Now adding the equations (1) and (3)


_______________


Therefore y=-1
Now substitute the value of y=-1 in the equation (1) we get
-2x+3(-1)=-9
-2x-3=-9
-2x=-9+3

Therefore x=3
The values of x and y to the given equation are x=3 and y=-1
The solution to the given equation is (3,-1)
