Given:
- [tex]r - 3 = 14.3\\[/tex]
What is an Equation?
An equation is a statement that two things are equal with an equal sign e.g. x + 1 = 10, 7 + 1 = 8, 9=9. What is on the left-hand side (LHS) is equal to what is on the right-hand side (RHS)
To find the area of computational error, let's try solving it step-by-step
First line: r - 3 = 14.3
It represents the equation from the main problem which Katy is trying to solve so it should be correct!
Second line: r - 3 + 3 = 14.3 - 3
There's an error as Katy was meant to subtract 3 from both sides to remove -3 from the RHS and balance the equation leaving the result of r
The resulting value is wrong due to the error from the previous step in Katy's solution
The correct solution
r - 3 = 14.3
r - 3 + 3 = 14.3 + 3
r = 17.3
