Edward solved the equation 4X + 1 = 5x +(-5) Add 4 negative both sides
Add 5 negative to both side
=4
What’s was mistake

He should have added 5 to each side instead of -5

Step-by-step explanation:

4X + 1 = 5x +(-5)

Subtract 4x from each side

4X-4x + 1 = 5x-4x +(-5)

Combine like terms

1 = x-5

Add 5 to each side  

He should add 5 to each side ( we need to add the opposite of (-5)) to undo the adding  of (-5)

1+5 = x-5+5

6 =x

da freeck kinda math is this just drop out

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
