40. If twice the value of a certain number is increased by 15, the result is 75
What strategy will you used to solve the problem?

Answer:

x = 30

--------------------------------------------------------------------------------------------------------------

Step-by-step explanation:

2x + 15 = 75

2x + 15 - 15 = 75 - 15 (subtract 15 on both sides)

2x = 60 (divide both sides by 2)

x = 30

check:

2(30) + 15 = 75

60 + 15 = 75

75 = 75
