Answer 3

To solve the equation, we need to find the value of 'x' that makes the equation true. To do that, we'll first combine the like terms on the left side of the equation:

(3/5)x + (2/3)x - 3 = 4/5

To combine the fractions, we need a common denominator for 5 and 3, which is 15.

So, let's convert the fractions with denominators 5 and 3 to fractions with a denominator of 15:

(3/5)x can be written as (3/5)x * (3/3) = (9/15)x (2/3)x can be written as (2/3)x * (5/5) = (10/15)x

Now, the equation becomes:

(9/15)x + (10/15)x - 3 = 4/5

Combine the 'x' terms:

(19/15)x - 3 = 4/5

Next, let's isolate the term with 'x' by moving the constant term (-3) to the right side of the equation:

(19/15)x = 4/5 + 3

To add 3 and 4/5, we need a common denominator, which is 5:

(19/15)x = (20/5) + (3/5) (19/15)x = (23/5)

Now, to solve for 'x', we'll multiply both sides by the reciprocal of (19/15), which is (15/19):

x = (23/5) * (15/19)

To simplify the right side, you can multiply the numerators and denominators:

x = (23 * 15) / (5 * 19) x = 345 / 95

So, the value of 'x' that satisfies the equation is:

x = 345/95 or approximately 3.63 (rounded to two decimal places).
