Answer 2

To solve the equation, follow these steps:

Step 1: Simplify the equation if possible. Step 2: Isolate the variable on one side of the equation. Step 3: Solve for the variable.

Let's solve the equation:

Step 1: Simplify the equation (if needed). To simplify the equation, convert the mixed number (1 2/3) into an improper fraction.

1 2/3 = (3 * 1) + 2 = 5/3

So, the equation becomes:

3/4x - 1.5 = 5/3 - 0.2

Step 2: Isolate the variable on one side. To isolate the variable (x), first, get rid of the constant term (-1.5) by adding 1.5 to both sides of the equation:

3/4x = 5/3 - 0.2 + 1.5

Step 3: Solve for the variable (x). Now, we can simplify the right-hand side of the equation:

3/4x = (5/3) + (1.5 - 0.2) = 5/3 + 1.3

Next, find a common denominator for 5/3 and 1.3, which is 3. Convert 1.3 to a fraction with a denominator of 3:

1.3 = 1 + 0.3 = 1 + 3/10 = 10/10 + 3/10 = 13/10

Now, the equation becomes:

3/4x = 5/3 + 13/10

To add these fractions, find a common denominator, which is 30:

(5/3)(10/10) + (13/10)(3/3) = 50/30 + 39/30 = 89/30

Now, the equation is:

3/4x = 89/30

To solve for x, multiply both sides by the reciprocal of 3/4, which is 4/3:

x = (89/30) * (4/3)

Now, multiply the numerators and denominators:

x = (89 * 4) / (30 * 3)

x = 356 / 90

x = 3.955555...

Since we have decimal places, round the answer to an appropriate number of decimal places (let's say two):

x ≈ 3.96

So, the solution to the equation is approximately x = 3.96.
