4 2154 Sölve (Es fall) :- x + 7-8x = 17 5x uliah OV = 7cm KA=5cm.

Solve:- 5x + 7 = 17

Solve : 5x - 7 = 2x+ 8

Solve : x+7-(8x)/(3)=(17x)/(6)-(5x)/(8)

5x+7=2x-8

Find the value of x , if x = 7/4 - 17/8

Solve the following: 3 (5x – 7) + 2(9x – 11) = 4(8x – 7) – 111

Add: 5x^(2) - 7x + 3, -8x^(2) + 2x -5 and 7x^(2) - x - 2

Construct square DEFG such that l (DE) = 4.5 cm, l (EF) = 6.5cm, l (DG) = 5.5 cm, l (DF) = 7.2 cm, l (EG) = 7.8 cm.

Simplify : 84 - 7[-11x - 4{-17x + 3(8-9+5x))}]
