3( x - 1 ) = 2 x + 5
Expand 3(x-1) :
3*x - 3 x 1
3 x - 3 = 2 x + 5
Add 3 both sides :
3 x - 3 + 3 = 2 x + 5 + 3
3 x = 2 x + 8
3x - 2 x = 8
x = 8

18 = .75x
/.75 /.75 (divide both sides by .75 to isolate x)
24 = x

Step-by-step explanation:
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
