Question

Math genius answer
Form equations and solve them to find the unknown number in each of the following:​

Answer 1

Step-by-step explanation:

According to the first condition

7 + 6x = 37

∴ 6x = 37 - 7

∴ 6x = 30

∴ x = 30/6

∴ x = 5

Therefore the answer to the first question is 5 .

According to the second condition

Let the first number be X

Then the second number is = x+ 5

Then the third number is = x+ 10

Now we are given that the sum of the three terms is 120.

∴ x + x+ 5 + x+ 10 = 120

∴ 3x + 15 = 120

∴ 3x = 120 - 15

∴ 3x = 105

∴ x = 105/3

∴ x = 35

Then the numbers are: 35, 40 , and 45.

According to the third condition

x - 10 = 20

∴ x = 20 + 10

∴ x = 30

Sorry couldn't solve the 4th one.
