1 answer:

3 0

Answer: If you are given ordered pairs and asked if they are solutions to the equation, substitute the values in for X and Y. See if the 2 sides equal. If they do equal, then that ordered pair is a solution. If they don't equal, then the ordered pair is not a solution.

2x + 1=4x-3 solve for x

loris [4]

Answer:

x = 2

Step-by-step explanation:

To start, you want to isolate x.

To do so, get all the x terms to one side.

2x + 1 = 4x - 3

Subtract -4x on both sides.

-2x + 1 = -3

Then, subtract 1 on both sides.

-2x = -4

Finally, divide -2 on both sides.

x = 2
