Solve for x 17 35 x 35 75 25x 5 5 a 130 b 215 c 110 d 16
Solve for x. 1/7 (35 x - 35) = 7/5 (25x - 5) + 5 a) 1/30 b) -2/15 c) -1/10 d) -1/6 e) -1/6 e) -1/5 f) None of the above.
Solution
(1/7(35x - 35) =7/5(25x - 5) +5
Taking out 35 outside the bracket from LHS:
Taking out 5 outside the bracket from RHS:
35/7(x-1) = 7*5/5(5x -1) +5
5(x-1) = 7(5x -1) +5
5x -5 = 35x -7 +5
-30x = -7 +10
-30x = 3
x = -1/10
Option c
