Answer:
x= −1/3 y+5/3
Step-by-step explanation:
Let's solve for x.
y=−3x+5
Step 1: Flip the equation.
−3x+5=y
Step 2: Add -5 to both sides.
−3x+5+−5=y+−5
−3x=y−5
Step 3: Divide both sides by -3.
−3x

The "x-intercept" occurs when y=0, because it is at this point that the equation touches the x axis. So if you plug in y=0 into the equation you can solve for the x coordinate.
4x-2(0)-8=0
4x-8=0
4x=8
x=2
So the x-intercept is the point (2,0)
Answer:
Step-by-step explanation:
In a parallelogram, diagonals bisect each other.
7y - 2 = 5y + 4
7y - 2 - 5y = 4
2y - 2 = 4
2y = 4 +2
2y = 6
y = 6/2
y = 3
3x +2 = 23
3x = 23 - 2
3x = 21
x = 21/3
x = 7
