Answer:

Explanation:

Steps to solve:

1. Write down the given information as a system of equations:

We are given that the length of the base is x, and the length of a leg is 5x-6. We are also given that the perimeter of the triangle is 98. We can use this information to write down the following system of equations:

x + 2(5x-6) = 98

2. Solve the system of equations:

We can solve the system of equations by using elimination. First, we can simplify the left side of the equation:

x + 10x-12 = 98

Next, we can combine the x terms on the left side of the equation:

11x-12 = 98

Then, we can add 12 to both sides of the equation:

11x = 110

Finally, we can divide both sides of the equation by 11 to solve for x:

x = 10

3. Interpret the solution:

The solution to the system of equations is x = 10. This means that the length of the base of the triangle is 10 units, and the length of a leg is 5(10)-6 = 44 units.

Answer:

x = 10
