Is this algebra problem correct?

stacy

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) − 4x = 4 − 3(x − 3)

Distribute:

6x + 3 − 4x = 4 − 3x + 9

Simplify:

2x + 3 = 13 − 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) − 4x = 4 − 3(x − 3)

3(2(2) + 1) − 4(2) = 4 − 3((2) − 3)

3(5) − 8 = 4 + 3

15 − 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!
