1. 3x-6=4x+5
2. 6x-3=0
3. 8x+2-6+10=0
4. 2x+6=0
5. 3(4x-5)+2(2x+6)=5x-12

Jawaban:

$3x - 6 = 4x + 5 \ 3x - 4x = 5 + 6 \ - x = 11 \ x = - 11$

$6x - 3 = 0 \ 6x = 3 \ x = frac{3}{6} \ x = frac{1}{2}$

$8x + 2 - 6 + 10 = 0 \ 8x - 4 + 10 = 0 \ 8x + 6 = 0 \ 8x = 6 \ x = frac{6}{8} \ x = frac{2}{3}$

$2x + 6 = 0 \ 2x = - 6 \ x = - 3$

$3(4x - 5) + 2(2x + 6) = 5x - 12 \ 12x - 15 + 4x + 12 = 5x - 12 \ 16x - 3 = 5x - 12 \ 16x - 5x = - 12 + 3 \ 11x = - 9 \ x = - frac{9}{11}$
