Answer:

x = -1

Step-by-step explanation:

10 - 7x - 5 + 12x = 0

➡️ 5 - 7x + 12x = 0

➡️ 5 + 5x = 0

➡️ 5 + 5x - 5 = 0 - 5

➡️ 5x = 0 - 5

➡️ 5x =  - 5

➡️ 5x \div 5 =  - 5 \div 5

➡️ x =  - 5 \div 5

➡️ x =  - 1

In an examination, 80 students secured
faust18 [17]

Number of students who secured first class in English only is 20

Step-by-step explanation:

  • Step 1: Find the number of students who secured first class in English only.

Total number of students who secured first class in English or Maths, T = 80

Number of students who secured first class in Maths, M = 50

Number of students who secured first class in both English and Maths, EM = 10

⇒ Let the number of students who secured first class in English only be x.

Total students with first class, T = M + EM + x

⇒ 80 = 50 + 10 + x

⇒ 80 = 60 + x

∴ x = 80 - 60 = 20
