Question

7-3(x-3)=x-2(x-1) solution

Answer 1

given :-

7 - 3(x - 3) = x - 2(x - 1)

➡ 7 - (3 × x) - (3 × -3) = x - (2 × x) - (2 × -1)

➡ 7 - 3x + 9 = x - 2x + 2

➡ 16 - 3x = -x + 2

➡ -3x + x = 2 - 16

➡ -2x = -14

➡ x = -14/-2

➡ x = 7

-: VERIFICATION :-

LHS :-

» 7 - 3(7 - 3)

= 7 - 3(4)

= 7 - 12

= -5

RHS :-

» x - 2(x - 1)

= 7 - 2(7 - 1)

= 7 - 2(6)

= 7 - 12

= -5

hence verified. the value of x = 7

Answer 2

7 - 3(x - 3) = x - 2(x - 1)

7 - 3x + 9 = x - 2x + 2

- 3x + 16 = - x + 2

- 3x + x = + 2 - 16

- 2x = - 14

x = 7
