Glad to help, but in my view "helping" means providing you with assistance only after you've begun your own efforts to solve these problems.

Look at    <span>3(k+5)=-2(3k-6).  Goal:  Solve for k.
Multiplying where indicated:

             3k + 15 = -6k + 12

Add 6k to both sides:         9k = 12 - 15

dividing both sides by 9:  k = -3/9, or    k = -1/3   (answer).

Please start one of the other solutions; ask if you have questions about it.</span>

5(2x - 3) + 2 (3x + 1)
astraxan [27]
     <span> 1/3(2x - 3) + 1 = 1/4(3x + 5) - 2
2x/3 - 3/3 + 1 = 3x/4 + 5/4 - 2
2x/3 - 1 + 1 = 3x/4 + 5/4 - 2
2x/3 - 3x/4 - 0 = 3x/4 - 3x/4 + 5/4 - 2
2x*4/3*4 - 3x*3/4*3 = 0 + 5*1/4*1 - 2*4/1*4
8x/12 - 9x/12 = 5/4 - 8/4
(8x - 9x)/12 = (5 - 8)/4
-x/12 = -3/4
-x/12 * 12 = -3/4 * 12
-x = -36/4
-x * -1 = -36/4 * -1
x = 36/4
x = 9
Done

For check the answer
let x = 9
1/3(2[9] - 3) + 1 = 1/4(3[9] + 5) - 2
1/3(18 - 3) + 1 = 1/4(27 + 5) - 2
1/3(15) + 1 = 1/4(32) - 2
15/3 + 1 = 32/4 - 2
15/3 + 3/3 = 32/4 - 8/4
18/3 = 24/4
6 = 6
therefor
x = 9 is a correct answer</span>
