2x - 3 = 8
add 3 to both sides
2x = 11
divide both sides by 2
x = 5.5
Answer:
80 - 12 - 5f
Step-by-step explanation:
You have a total of eighty seeds in all.
Minus the twelve seeds Demi planted.
The number of friends she gave seeds to is unclear.
To find out how many seeds she gave you'd have to
multiply five by the number of friends.
It's is all being subtracted from the total.
Hope this helps. ;)

Answer:</h3>
y = -5x -1
<h3>
Step-by-step explanation:</h3>
Changes in x-values are constant and are +1.
Changes in y-values are constant and are -5.
Because the ratio of changes in y to changes in x is constant (-5/1) = -5, you know the function is linear. To write the equation, you can use the slope-intercept form, since you know the slope (-5) and the table shows the y-intercept: (x, y) = (0, -1).
The rule is ...
... y = -5x -1
If xy=0
assume that at least x or y=0
3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3
