Answer:
x = 14/5
Explanation:
To solve the equation x/7 = 2/5 for x, we can use the property of equality that allows us to multiply or divide both sides of the equation by the same non-zero number. In this case, we want to isolate x on one side of the equation, so we can multiply both sides by 7 to get:
x/7 * 7 = 2/5 * 7
Simplifying the left-hand side, the 7s cancel out on the left-hand side, leaving us with:
x = 2/5 * 7
Multiplying 2/5 by 7, we get:
x = 14/5
Therefore, x = 14/5 is the solution to the equation x/7 = 2/5.
