Question

Kaitlyn solved the equation for x using the following calculations. Negative 5. 4 x = 12. 2. Minus 5. 4. X = 6. 8. What error, if any, did she make? She should have added 5. 4 to each side. She should have added the inverse of 5. 4 to each side. She made a computational error when she subtracted 5. 4 from 12. 2. She should have added 12. 2 to each side.

Answer 1

The value of x is 17.6. She should have added 5.4 on both sides to get the correct value of x. Then the correct option is A.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Kaitlyn solved the equation for x using the following calculations.

$\rm -5.4 + x =12.2$

and she did the calculation will be

$\rm -5.4x = 6.8$

The mistake she did in this equation is the plus sign is removed between the -5.4 and x. And she subtracted 5.4 from 12.2.

The correct solution of the equation is to add both sides 5.4. Then we have

$\begin{aligned} \rm -5.4 + x+5.4 &=12.2+5.4\\\\\rm x &= 17.6\end{aligned}$
