If `5x + 2(x + 7) = 14x – 7`. Find x

5x + 2(x + 7) = 14x – 7. Find 3x - 6 ?

Find the facors of (x^(2) + x - 42) A. (x + 14) ( x - 3) B. ( x + 6) ( x - 7) B. ( x - 6 ) ( x + 7) D. ( x - 14) ( x + 3)

(i) x=14-y. Find x ,If y=8 . (ii) y=x-2 . Find y ,if x=7 .

Solve : (3x +4)/(7) - (x +5)/(14) = (x)/(28) + (x +1)/(14) The following steps are involved in solving the above problem. Arrange them in sequential order (A) 5x + 3 = (3x + 2)/(2) rArr 10 x + 6 = 3x + 2 (B) rArr 7x = -4 (C) Given (3x + 4)/(7) - (x + 5)/(14) = (x)/(28) + (x +1)/(14) rArr (6x + 8 -x -5)/(14) = (x + 2x + 2)/(28) (D) rArr x = -(4)/(7)

2. Multiply: (3x +5) (2x +7). 3. Find (7x-2)(5x-8) by inspection.

If 5x = 3(mod 7) then find x
