Answer 3

To solve the equation `(4x-5)/3 - (7x+3)/9 = -2`, we can follow these steps:

Step 1: Simplify the equation by finding a common denominator for the fractions on the left side. In this case, the common denominator is 9.

`(4x-5)/3 - (7x+3)/9 = -2`

Multiply the first fraction by 3/3 and the second fraction by 1/1 to obtain a common denominator:

`(4x-5)*(3/3) - (7x+3)*(1/1) = -2`

Simplifying the equation gives:

`(12x - 15)/9 - (7x + 3)/9 = -2`

Step 2: Combine the fractions on the left side of the equation by subtracting them:

`(12x - 15 - (7x + 3))/9 = -2`

Simplify the expression within the parentheses:

`(12x - 15 - 7x - 3)/9 = -2`

Combine like terms:

`(5x - 18)/9 = -2`

Step 3: Multiply both sides of the equation by 9 to eliminate the fraction:

`9 * (5x - 18)/9 = -2 * 9`

Simplifying gives:

`5x - 18 = -18`

Step 4: Add 18 to both sides of the equation to isolate the variable term:

`5x - 18 + 18 = -18 + 18`

Simplifying gives:

`5x = 0`

Step 5: Divide both sides of the equation by 5 to solve for x:

`(5x)/5 = 0/5`

Simplifying gives:

`x = 0`

Therefore, the solution to the equation `(4x-5)/3 - (7x+3)/9 = -2` is `x = 0`.
