0.02x = 40 what is X step by step explanation

Korolek [52]

Answer:

2000

Step-by-step explanation:

In the equation, there is 0.02 attached to the x. This means multiplication. TO get rid of the 0.02, you need to do the opposite of multiplication. That is division.

Divide both sides by 0.02.

$\frac{0.02x}{0.02} =\frac{40}{0.02}$

$x=2000$

What is x and y equal in: -2X-y=3 and x+2y=4 (find x and y using elimination)

makvit [3.9K]

-2x-y=3 ...(1)
x+2y=4 ...(2)
multiply (2) by 2 and add to (1)
-2x-y+2x+4y=3+8
3y=11
y=11/3
from (2)
x=4-2y=4-2(11/3)
or x=4-(22/3)
=(12-22)/3=-10/3
