1 answer

To find the solution to the equation 2f/5 - 8/5 + 2f = 8, we can simplify the equation step by step using the properties of equality.

Step 1: Start by simplifying the fractions on the left side of the equation. The common denominator for the fractions is 5, so we can rewrite the equation as:

(2f + (-8) + 2f) / 5 = 8

Simplifying further gives us:

(4f - 8) / 5 = 8

Step 2: Multiply both sides of the equation by 5 to eliminate the denominator:

5 * (4f - 8) / 5 = 8 * 5

This simplifies to:

4f - 8 = 40

Step 3: Add 8 to both sides of the equation to isolate the variable:

4f - 8 + 8 = 40 + 8

This simplifies to:

4f = 48

Step 4: Divide both sides of the equation by 4 to solve for f:

4f / 4 = 48 / 4

This gives us:

f = 12

So, the solution to the equation 2f/5 - 8/5 + 2f = 8 is f = 12.
