Standard form is ax+by=c
Steps:
y + 4 = 1.5(x - 4)
y + 4 = 1.5x - 6
-1.5x + y = -10 is the standard form.
Answer:
x = 70/9 :)
Step-by-step explanation:
So, 9(x - 9) = -11. :)
We can use the distributive property to turn 9(x - 9) into 9x - 81!
9x - 81 = -11
We can now add on 81 to both sides :)
9x = -11 + 81 = 70
So, we have 9x = 70.
To get x by itself, we'll divide the equation by 9, to get:
9x / 9 = 70 / 9
x = 70/9
And there's your solution :)
