1. Problem Description

We are asked to solve the equation 6(3x4)10(x3)=10(2x3)6(3x-4) - 10(x-3) = 10(2x-3) for xx.

2. Solution Steps

First, we distribute the constants outside the parentheses into the terms inside the parentheses.
6(3x4)=6(3x)6(4)=18x246(3x-4) = 6(3x) - 6(4) = 18x - 24
10(x3)=10(x)10(3)=10x+30-10(x-3) = -10(x) - 10(-3) = -10x + 30
10(2x3)=10(2x)10(3)=20x3010(2x-3) = 10(2x) - 10(3) = 20x - 30
Substituting these back into the original equation gives:
18x2410x+30=20x3018x - 24 - 10x + 30 = 20x - 30
Now, we combine like terms on the left side of the equation:
(18x10x)+(24+30)=20x30(18x - 10x) + (-24 + 30) = 20x - 30
8x+6=20x308x + 6 = 20x - 30
Next, we want to isolate the xx terms. We can subtract 8x8x from both sides of the equation:
8x+68x=20x308x8x + 6 - 8x = 20x - 30 - 8x
6=12x306 = 12x - 30
Now, we add 3030 to both sides of the equation:
6+30=12x30+306 + 30 = 12x - 30 + 30
36=12x36 = 12x
Finally, we divide both sides by 1212 to solve for xx:
3612=12x12\frac{36}{12} = \frac{12x}{12}
3=x3 = x
So, x=3x=3.

3. Final Answer

x=3x = 3
