Answer:
Step-by-step explanation:
x^2 - 4x + 20 = 0
x^2 - 4x = -20
x^2 = 4x - 20
x = 2x - 4.47
-3x = -4.47
x = roughly 1.5
Answer:
-25.49
Step-by-step explanation:
(-3.8)+(-21.14)+(-0.55)
-3.8-21.14-0.55
-25.49
To solve for x, you undo what was done to x. The variable x is ...
- multiplied by y
- added to z
You "undo" these operations in the reverse order, so first we undo the addition of z. We accomplish that by adding the opposite of z:
... -10 -z = xy
Now, we undo the multiplication by y. We accomplish that by multipying by the reciprocal of y.
... (-10 -z)/y = x
We can rearrange this, if you like.
And, if you want, you can factor out the minus sign.
