Math Problem Statement

-(1/3)x + 1 = (3/2)x - 1

Solution

The equation in the image is:

13x+1=32x1-\frac{1}{3}x + 1 = \frac{3}{2}x - 1

Let's solve for xx:

Step 1: Eliminate the fractions

To make the equation easier to work with, multiply through by the least common denominator (LCD) of 3 and 2, which is 6:

6(13x+1)=6(32x1)6 \left(-\frac{1}{3}x + 1 \right) = 6 \left(\frac{3}{2}x - 1 \right)

Distribute the 6:

2x+6=9x6-2x + 6 = 9x - 6

Step 2: Move all terms involving xx to one side

Add 2x2x to both sides:

6=11x66 = 11x - 6

Step 3: Move constant terms to the other side

Add 6 to both sides:

12=11x12 = 11x

Step 4: Solve for xx

Divide both sides by 11:

x=1211x = \frac{12}{11}

So, the solution is:

x=1211x = \frac{12}{11}
