Answer:
x=5
Step-by-step explanation:
distribute first
2(-4x+3)
-8x+6
-8x+6+3x+3=-16
combine like terms
then get the variable alone
-5x+9=-16
-9. -9
<u>-5x</u><u>=</u><u>-25</u>
-5. -5
x=5
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
Answer: She is incorrect because 0 + 0 = <u>0</u>
0.057x 10 is equal to .57. All you have to do is move the decimal to the right one time because there is one zero in 10.
