1. Problem Description

The problem is to solve the following linear equation for xx:
310x32=45x+1\frac{3}{10}x - \frac{3}{2} = \frac{4}{5}x + 1

2. Solution Steps

First, we want to isolate terms with xx on one side of the equation and constant terms on the other side. Subtract 310x\frac{3}{10}x from both sides:
32=45x310x+1-\frac{3}{2} = \frac{4}{5}x - \frac{3}{10}x + 1
32=810x310x+1-\frac{3}{2} = \frac{8}{10}x - \frac{3}{10}x + 1
32=510x+1-\frac{3}{2} = \frac{5}{10}x + 1
32=12x+1-\frac{3}{2} = \frac{1}{2}x + 1
Next, subtract 1 from both sides:
321=12x-\frac{3}{2} - 1 = \frac{1}{2}x
3222=12x-\frac{3}{2} - \frac{2}{2} = \frac{1}{2}x
52=12x-\frac{5}{2} = \frac{1}{2}x
Now, multiply both sides by 2 to solve for xx:
2(52)=2(12x)2 \cdot (-\frac{5}{2}) = 2 \cdot (\frac{1}{2}x)
5=x-5 = x
So, x=5x = -5.

3. Final Answer

x=5x = -5
