Question

Prove that: 25 × 2x− 4 5− 2 ×10 x− 6 = 1252​

Answer 1

Answer:

25 × 2x - 45 - 2 × 10x - 6 = 1252

50x - 45 - 20x - 6 = 1252

50x - 20x - 45 - 6 = 1252

30x - 45 -6 = 1252

30x - 51 = 1252

30x = 1252 + 51

30x = 1303

x = 1303/30

x = 43.433

Answer 2

(25*2x) - 45 - (2x 10x) -6 = 1252
50x -20x - 51 = 1252
30x. = 1252+51
x. = 1303/30
= 43.4333
(25*2*43.4333)-45-(2* 10* 43.4333)-6
=1252
