Question

One of the zookeepers solved to find Bernard’s speed when he is healthy using the equation: x â€" 41. 5 = 13. 5. The other zookeeper said that to solve for Bernard’s speed when he is healthy, they must use the equation: 41. 5 13. 5 = x. Which zookeeper is correct? Explain.

Answer 1

The equations of both the zookeepers are correct as well as the same, where x = 55.

Given to us,

equation is given by the first zookeeper,  ${x-41.5 = 13.5}$

equation is given by the second zookeeper,  ${41.5 + 13.5=x}$

Solving both equations to find out the value of x, we get,

For the first zookeeper,

${x-41.5 = 13.5}\\x=41.5+13.5\\x=55$

For the second zookeeper,

${41.5 + 13.5=x}\\x = 55$

Hence, the equations of both the zookeepers are correct as well as the same, where x = 55.
