Answer 3

To solve the equation 3.2x + 5.6 + 5.8x = 17.21, we need to find the value of x that makes the equation true.

Step 1: Combine like terms. 3.2x + 5.8x can be combined as (3.2 + 5.8)x = 9x.

Step 2: Rewrite the equation with the combined terms. So the equation becomes 9x + 5.6 = 17.21.

Step 3: Isolate x on one side of the equation. To isolate x, we need to get rid of the constant term on the left side of the equation. We can do this by subtracting 5.6 from both sides of the equation:

9x + 5.6 - 5.6 = 17.21 - 5.6 9x = 11.61

Step 4: Solve for x. To solve for x, divide both sides by 9:

x = 11.61 / 9 x ≈ 1.29

So the value of x that satisfies the equation is approximately 1.29.
