Can someone explain this to me? thx

In the first equation (2x+3), if you plug in the 3 for X, you get 9.

2(3)+3
6+3=9.

In the second equation (3x+1), if you plug in 3 for X, you get 10.

3(3)+1
9+1=10.

Therefore, no, the expressions are not equal when x=3.

When you plug in 2 for X in (2x+3), your answer will be 7.

2(2)+3
4+3=7.

When you plug in 2 for X in (3x+1), your answer will be 7.

3(2)+1
6+1=7.

Therefore, yes, the equations are equal when x=2.

If you do the same process for x=1, you will find that the equations are not equal when x=1.

I hope this helped. Best of luck!

Dwould be the answer
