Name Grades.

1. Simple type.

x－ x= 2x + = 70%x+ 20%x = x×=20× 25% +10x =

x -15%x =68 x＋x＝121 5x－3×＝ x÷＝12 6x＋5 =

x + x = 4 4x－3 ×9 = 29 x＋x= 4x－6×=2

x = x = × x÷ =×

Second, there are many equations on one side of the equation.

For this kind of equation, we should first calculate what can be calculated according to the arithmetic law.

3. Equations with parentheses.

For questions with parentheses, we generally remove the parentheses first, and then calculate them according to the above method.

4. Equations using the multiplicative distributive law.

Apply the multiplicative distributive property first, then remove the parentheses.

5. There are equations for x on the left and right.

Depending on the nature of the equation, the x on one side of the equation is eliminated and proceed according to the steps described above.

Sixth, comprehensive application.

Do you want a decimal, or an integer.

1. Calculate 20 questions, add 5 points if you are right, deduct 3 points if you are wrong, and get 60 points. (Correct a few questions).

2. Three contestants participate in the competition, 10 points will be scored for a correct answer, and 8 points will be deducted for incorrect answers.

Player No. 1 answered 8 questions and scored 44 How many answers did you get right? How much is wrong?

Player 2 answered 10 questions and scored 46 How many answers did you get right? How much is wrong?

Player No. 3 answered 9 questions and scored 72 How many answers did you get right? How much is wrong?

A riddle was guessed by 60 people, a total of 338 people guessed correctly, each person guessed at least 3 songs correctly, 6 people guessed 3 correctly, 10 people guessed 4 correctly, and the number of people who guessed 5, 6, and 7 correctly was the same. How many of the 8 guesses are correct.

Question 1: If x is correct, then (20-x) is incorrect, then there is 5x-3(20-x)=60 and x=15

Question 2: The principle is the same as the first question. (1) 6 correct answers, 2 incorrect answers, (2) 7 correct answers, 3 incorrect answers, (3) 8 correct answers, 1 incorrect answer.

Question 3: If there are x people who answer 5, 6, and 7 correctly, then there are (60-6-10-3x=44-3x) people who answer 8 correctly, then there are 338-3*6-4*10-3x=8(44-3x) and x=12 44-3x=8

So 8 out of 8 guessed correctly.
