these are all right it shows me the answers in the review so even though i got some wrong i could still give the right answers here.

Answer 1

One solution.

Explanation:

So we have:

2x + 3 = 4x + 2

Simplifying gives;

4x - 2x = 3 - 2

2x = 1

x = 1/2

There is only one solution here.

*Note: This questions are simple. You just have to do a little more practice on algebra if you are stuck.
