jika 3(x+2) +5 =2 (x+15) maka nilai dari (x+2)=

cari dulu x nya..

3(x+2) + 5 = 2 (x+15)
3x + 6 + 5 = 2x + 30
3 x + 11 = 2x + 30
3 x - 2 x = 30 - 11
x = 19


nilai x + 2 = 19+2 = 21

semoga membantu:)

penyelesaian :

= 3 ( x + 2 ) + 5 = 2 ( x + 15 )

= 6 + 3 x + 5 = 2 x + 30

= 3 x + 11 = 2 x + 30

= 3 x - 2 x = 30 - 11

<=> x = 19

( x + 2 ) = 19 + 2 = 21


Semoga membantu
