Answer:
x=4 y=0
Step-by-step explanation:
3x+5y=12
-(x-3y=4)
3x+5y=12
3(-x+3y=-4)
3x+5y=12
-3x+9y=-12
14y=0
y=0
Then, substitute the y into the equation to find x
x-3(0)=4
x=4

Answer:
y = -3/2x + 6
Step-by-step explanation:
We won't be able to figure out Y in number form, since we have a second variable, but we can figure it out in terms of X.
First, we have to subtract 6x from both sides
( -4y = -6x + 24 )
Then we have to divide both sides by -4
( y = -3/2x + 6 )
This is our final answer in terms of x
Answer:
c-12
Step-by-step explanation:
Pythagoras theorem states that a²+b²=c²
144+b²=c²
b²=c²-144
b=c-12
b=x
x=c-12
