Question

`d - 23.6 = 24.9 \\ a.d = 47.5 \\ b.d = 48.5 \\ c.d = 1.3 \\ d.d = 2.3`

Answer 1

Hello there! :)

Explanation:

Solving One-Step Equations: Addition and Subtraction.

Addition property of equality is adding the same number to both sides of an equation does not change the equation.

`a+c=b+c`

First, you add by 23.6 from both sides of an equation.

`d-23.6+23.6=24.9+23.6`

And then solve or simplify.

`24.9+23.6=48.5`

Answer: →
`\boxed{d=48.5}` and
`\boxed{B.}`

Hope this helps!

Thanks!

Answer 2

`d-23.6=24.9\qquad\text{add 23.6 to both sides}\\\\d+23.6-23.6=24.9+23.6\\\\\boxed{d=48.5}\to\boxed{b.}`
