Answer:

x = 5

Explanation:

We have


(x+3)/(2) - (3x+1)/(4) = (2(x-2))/(3) -2

We can start by expanding the 2(x-2) into 2x-4


(x+3)/(2) - (3x+1)/(4) = (2x-4)/(3) -2

Next, we can remove denominators. We can start by multiplying both sides by 4. We do this because 2 (another denominator) is a factor of 4, so multiplying by 4 will remove both the denominator of 2 and the denominator of 4, resulting in


2x+6 - (3x+1) = (4*(2x-4))/(3) -4(2)

We can then simplify and expand


-x+5 = (8x-16)/(3) -8

We can then multiply both sides by 3 to remove the other denominator


-3x+15 = 8x-16 - 24\\= 8x-40

We then have

-3x+15 = 8x-40

We can start by adding 3x to both sides to make all the x values and their coefficients on one side, resulting in

15 = 11x - 40

We can then add 40 to both sides to isolate the x values and their coefficients, resulting in

55 =11x

We can finally divide both sides by 11 to isolate x

x = 55/11 = 5
