Deketahui k merupakan penyelesaian persamaan 3(x + 2) - 4 (1 - x) = -19. Nilai k + 1 adalaj

3x + 6 - 4 + 4x = -19
3x + 4x = -19 - 6 + 4
7x = -21
x = -21 / 7
x = -3

jadi, k = -3
Nilai k + 1 = -3 + 1 = -2


semoga membantu

3(x+2) - 4(1-x) = -19
3x + 3.2 + -4.1 + -4.(-x) =-19
3x + 6 - 4 + 4x = -19
3x + 4x + 6 - 4 = -19
7x + 2 = -19
7x = -19 - 2
7x = -21
x = -21/7
x = -3

k = x = -3
k+1 = -3 + 1
= -2
