3(2x - 3) = 4x + 1<br> Help
lesantik [10]

Answer:

x=5

Step-by-step explanation:

You first have to distribute. So multiply the 3 with whats inside the parenthesis. So 3 times 2x is 6x. And 3 times -3 is -9. That means that so far you have 6x-9. Now on the other side you have 4x+1. So you move the 9 over to the other side by doing the opposite of it. Meaning +9. So you add 9 to 1 giving you 10. Now you have, 6x=4x+10. Just subtract 4x from 6x, which gives you 2x. Lastly, you divide the 10 by 2x because division is the opposite of multiplication
