Question

R - 17.1 = -4.8

Please show work. I kinda get how to do these problems but I don’t understand how the answer is 12.3. I got 34.2

Answer 1

Answer: r=12.3 *The answer must have a  positive sign or decimal point.*

Explanation:

First, you had to do is add 17.1 from both sides of an equation.

$r-17.1+17.1=-4.8+17.1$

And then, simplify by equation.

$17.1+-4.8=12.3$

You can also add by the numbers.

$12.3+4.8=17.1$

$r=12.3$

Hope this helps!
