Jen solved the equation 100 minus one-half x equals 92 to determine the number of questions, x, she answered incorrectly on a test. She began by subtracting 100 from both sides, then multiplying both sides by –2. Which best describes the accuracy of Jen’s work? Incorrect. She needed to add 100 to both sides instead of subtracting 100. Incorrect. She needed to multiply both sides by –2 first, then subtract 100. Correct. She could have also subtracted 100 from both sides, then divided by Negative one-half. Correct. She could have also multiplied both sides by –2 first, then subtracted 100.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y
