You can always add or subtract
same value to/from both sides of equation. The same is true about multiplication and division.
In your case you have to subtract
x from both sides of equation in order to get rid of it on the left side:


But it's easier to remember that if you want to move some member of equation to other side, you just have to
change it's sign. Let's practice a bit using your equation (I have added "plus" signs where they are usually omitted to better understend what's going on):

Move
2y to the right side:

Move
8 to the left side:

Move both
x and
2y to the right side:
24 goes into 108 4.5 times, or 9/2 times, or 4 1/2 times
Answer:
Her mistake is that she should plot the point (0, 5) first, not (1, -3)
Step-by-step explanation:
First I simplified the equation given.
y - 3 = 2 (x + 1)
y - 3 = 2x + 2
+3 +3
y = 2x + 5
Since 5 is our y-intercept we would want to graph that first, which would be (0, 5) as a point.
Hope this helps!
Answer:
x = -1.5
Step-by-step explanation:
(0.5x+1.2)–(3.6–4.5x)=(4.8–0.3x)+(10.5x+0.6)
*I would first change any minus signs that are outside of the parenthesis to a plus sign. This is optional, not necessary. *
0.5x + 1.2 + (-3.6) + 4.5x = 4.8–0.3x + 10.5x + 0.6
*Now combine like terms on each side. *
5x + (-2.4) = 10.2x + 5.4
*move all Xs on one side.*
-5.2x = 7.8
*Divide both sides by -5.2 to get X by itself."
x = -1.5
