Question

(x+2) la a 2= 4 (x+3) ; (x-3)la a 2 =3 (9-2x) ;(2x+1)-3 (x+2) la a 2= 2 (7-4x);(2x+1) la a 2 =4(x+7)

Answer 1

(x+2)la a 2=x la a 2 +4x+4=4x+12

x la a 2 +4x-4x=12-4

x la a 2=8

x=√8

x=2√2

(x-3)la a 2=3(9-2x)

x la a 2 -6x+9=27-6x

x la a 2-6x+6x=27-9

x la a 2=18

x=√18

x=3√2

(2x+1)-3(x+2) la a 2=2(7-4x)

2x+1-3(x la a 2 +4x+4)=14-8x

2x+1-3x la a 2 -12x-12=14-8x

2x-3x la a 2-12x+8x=14+12-1

-2x-3x la a 2=25


(2x+1)la a 2=4(x+7)

4x la a 2 +4x+1=4x+28


4x la a 2 +4x-4x=28

4x la a 2 =28

x la a 2=7

x=√7
