8x + -6y = -20
</span><span>Solving
8x + -6y = -20
</span><span>Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right
</span><span>Add '6y' to each side of the equation.
8x + -6y + 6y = -20 + 6y
</span><span>Combine like terms: -6y + 6y = 0
8x + 0 = -20 + 6y
8x = -20 + 6y

Divide each side by '8'.
x = -2.5 + 0.75y

x = -2.5 + 0.75y</span>
Divide by all the numbers
Answer:
Step-by-step explanation:
The equation of a direct variation is generally written as:
Where m is the slope of the equation of the direct variation line.
We want a direct variation equation that contains (6,-2).
We substitute the x=6 and y=-2 to find m.
Divide both sides by 6.
The required equation is
Yes they are because they share the same variables and you can add the numbers.
