Diketahui persamaan 5(2x + 3)-4 = 6x-5. Nilai 2x+5

5(2x+3)-4 = 6x - 5
10x + 15 - 4 = 6x - 5
10x + 11 = 6x - 5
10x + 11 - 11 = 16x - 5 - 11
10x = 6x - 16
10x - 6x = 6x - 6x - 16
4x = -16
x = -16/4
x = -4

2x + 5
= 2(-4) + 5
= -8 + 5
= -3

5(2x + 3)-4 = 6x -5 
10x + 15-4 = 6x -5
10x -6x = -5-11
4x         = -16
x           = -4

nilai 2x +5 = 2. -4 + 5
                 = -8 + 5
                = -3

maaf kl salah
