Question

solve :- 1) 2(t-1)+6=102.
2) 2x -1/2=3​

Answer 1

1)2t-2+6=102

2t+4=102

2t=102-4

2t=98

t=98/2

t=49

2)2x=3+1/2

2x =7/2

X=7/2×2

X=7/4

Answer 2

1) 2(t-1)+6=102

➡️ 2(t-1) = 102 - 6

➡️ 2(t-1) = 96

➡️ t-1 = 96/2

➡️ t-1 = 48

➡️ t = 48 + 1

➡️ t = 49 ans.

2). 2x - 1/2 = 3

➡️2x = 3 + 1/2

➡️ 2x = (6+1)/2

➡️2x = 7/2

➡️x = (7/2)*(1/2)

➡️ x = 7/4 ans.
