Question

Jika 3(x-2)+4=5x+2,Maka nilai dari 2x+5

Answer 1

3(x-2) +4 = 5x + 2
3x -6 + 4 = 5x + 2
3x -5x = 2 + 6 - 4
     -2x = 4
        x = 4/-2
        x = -2
nilai dari 
2x+5 = 2(-2)+5
         = -4+5
         = 1

Answer 2

3(X-2)+4=5X+2
3X-6+4=5X+2
3X-2=5X+2
3X-5X=-2+2
-2X=0

Maaf yaaa kalo salah^^
