Is this algebra problem correct?
Solve for x: 3(2x + 1) - 4x = 4 - 3(x - 3)
*answer x=12/5
Update:ok I see where I messed up I did not multiply the 3 instead I put a 1. let me see if I get the same thing now.,
Update 3:ok I got it thanks so much for ya'lls help I did not distribute the 3 correctly so now I have it thanks again!

3(2x + 1) - 4x = 4 - 3(x - 3)
6x + 3 - 4x = 4 - 3x + 9
2x + 3 = -3x + 13
5x = 10
x = 2
Given:
3(2x + 1) â 4x = 4 â 3(x â 3)
Distribute:
6x + 3 â 4x = 4 â 3x + 9
Simplify:
2x + 3 = 13 â 3x
Add 3x to both sides:
5x + 3 = 13
Subtract 3 from both sides:
5x = 10
Divide by 5:
x = 2
Check
3(2x + 1) â 4x = 4 â 3(x â 3)
3(2(2) + 1) â 4(2) = 4 â 3((2) â 3)
3(5) â 8 = 4 + 3
15 â 8 = 7
7 = 7
This is true, thus we have the correct answer.
I get x = 2
checking my result
2x + 3 = 4 - 3x + 9
3 = 4 - 5x + 9
3 = 13 - 5x
5x = 10
x = 2
substituting x = 2 into original
3(4 + 1) - 8 = 4 - 3(2 - 3)
7 = 4 - 6 + 9
13 - 6 = 7
check, double check, Q.E.D.
x=2
get rid of () first: 3*2x+1*3-4x=4-3*x-3*3
6x+3-4x=4-3x+9
2x+3=13-3x
5x+3=13
5x=10
x=2
then check your answer:
3(2*2+1)-4*2=4-3(2-3)
3*5-8=4*3
7=7
I havent done algebra in a while but i believe jesse is right good luck
Good you've seen it, the answer is 2!
