diketahui persamaan 3(x + 2) - 4(1 - x)= - 19 nilai x + 1 adalh....

3(x + 2) -4 (1 - x) = - 19
3x + 6 -4 + 4x = -19
3x + 4x + 2 = -19
7x = -19 - 2
7x = -21
x = -3
x + 1 = -3 + 1 = -2

3(x+2)-4(1-x) = -19
3x + 6 - 4 + 4x = -19
7x + 2 = -19
7x = -19 -2
7x = -21
x = -21 ÷ 7 = -3

Jadi, x + 1 = -3 + 1 = -2

semoga membantu:))
