Answer: He is Incorrect, It's 38
Work: For this question, I did the Cross-Product Method. The Cross Product Method is when you solve equation via to fractions. With the CPM, One one side of the fraction, I had x / 20 (Twenty being the whole number) and on the other side, I had 190/100 (190 being the percent) After setting this up, I made the equation. 190 times 20 is 3800, and the other multiplication is 100 times x which is 100x. So, the new equation is 3800 = 100x. I divided both sides by 100, and the answer is 38 = x

Answer: x = -3/k</h3>
==============================================
Work Shown:
kx+7 = 4
kx+7-7 = 4-7 .... subtract 7 from both sides
kx = -3
kx/k = -3/k .... divide both sides by k
x = -3/k
The value of k cannot be zero. As the steps show, we are following PEMDAS in reverse to undo each operation to help isolate x. Subtraction is the opposite of addition, and division is the opposite of multiplication.
