Match the equation with the step needed to solve it.
ziro4ka [17]

To solve this, you need to isolate/get the variable "m" by itself in the equation:

1. 2m - 1 = 3m    Subtract 2m on both sides to get "m" on one side of the equation

2m - 2m - 1 = 3m - 2m

-1 = m

2. 2m = 1 + m     Subtract m on both sides to get "m" on one side of the equation

2m - m = 1 + m - m

m = 1

3. m - 1 = 2       Add 1 on both sides to get "m" by itself

m - 1 + 1 = 2 + 1

m = 3

4. 2 + m = 3   Subtract 2 on both sides to get "m" by itself

m = 1

5. -2 + m = 1      Add 2 on both sides to get "m" by itself

m = 3

6. 3 = 1 + m     Subtract 1 on both sides to get "m" by itself

2 = m

For the diagram below figure b is a reflection of y=2x of the line y =x
Scilla [17]
The equation of the line would be y = (1/2)x.

To find the equation of a line that is reflected through the line y = x, we just switch the x and y. Then, solve for y.

y = 2x
x = 2y
0.5x = y
