Question

Fiona was thinking of a number. Fiona doubles it and adds 5.1 to get an answer of 11.5. Form an equation with x

Answer 1

The equation is 2x + 5.1 = 11.5

Explanation:

Given that:

Fiona thinks of a number.

Let,

x be that number.

She doubles the number, therefore

2x

Then she adds 5.1 in the number, thus

2x + 5.1

She gets the answer 11.5, so the equation becomes

2x + 5.1 = 11.5

Hence,

The equation is 2x + 5.1 = 11.5
