Step-by-step explanation:
sorry cant help
3x4=12 1x12=12 6x2=12
You just need to be able to multiply the sides to equal 12. I hope that helps. :)
Answer:
-30
Step-by-step explanation:
-|-30-(10-20)|-|5-(10-15)|=-|-30-(-10)|-|5-(-5)|
=-|-30+10|-|5+5|
=-|-20|-|10|
=-(20)-(10)
= -20-10
= -30
This is a system of equations.
First, you set everything in terms of y.
Take the first equation and move set everything equal to y
y=0+2x
Since it’s 0, you don’t need to put it, so
y=2x works.
Then, you plug y=2x into the bottom equation, for the y.
-7x +3(2x)=2. You do this because now you have the same variable for both and it can be solved easily.
Then you can simplify.
-7x+3x = 2
Then combine like terms.
-4x = 2
Divide by -4 on each side.
x = -1/2
So, now that you have x, you can plug in your x-value back into the top equation.
-2(-1/2) + y = 0
Combine like terms
1+y=0
Get y by itself
y=-1
There you have it!
You can check by plugging in both values to any of the equations. We will use the top one here.
-2(-1/2) + (-1) =0
+1 + -1 = 0
It works!
So,
X= -1/2
Y= -1
