If you have a problem like:
4x+2y=20
2x+2y=16
You would subtract
4x-2y=20
-2x+2y=16
You would get the new problum
2x=4
You now want to divide the 2 on both sides to solve for x
x=2
Now that you've solved for X you want to solve for y. So use substitution to solve for y. You would want to substatute the x for the 2 in either of the problums. I'll use the first one.
4(2)+2y=20
You first want to multiply te 4(2) you would get a new problum.
8+2y=20
Now you want to subtract the 8 on both sides.
2y=12
The last step to solve for y is to divide the 2 on both sides.
Y=6
So your answers would be
x=2
y=6
Hello there!
Answer:
You can also round up to the nearest tenths is 15.1 to 15.0 and its going to be stay.
Step-by-step explanation:
First you had to switch sides of equation form.
Then you add by 0.3 from both sides of equation form.
And finally, simplify by equation. You can also cross out by -0.3+0.3 and it gave us equal to zero. Then you add 14.8+0.3 and it equal to 15.1. You had to used their variable and its should be the right answer.
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.

(18-7x)+1= -9 Hope this helps ^^
Hey there!!!
Given equation - 3x+6y
x is given as -3
y is given as 6
Plugin these values to get the final answer
3 ( -3 ) + 6 ( 6 )
-9 + 36
= 27
27 is the final and the required answer
Hope my answer helps!
I dont have the * exact answer * but i got 11 or 12. Hope this helps :))
