Question

6 + 8x = -x + 33
-12x - 18 + 9x = -9

Answer 1

$6 + 8x = - x + 33 \ 8x + x = 33 - 6 \ 9x = 27 \ x = frac{27}{9} \ x = 3$

$- 12x - 18 + 9x = - 9 \ - 3x = - 9 + 18 \ - 3x = 9 \ x = frac{9}{ - 3} \ x = - 3$

Answer 2

1) 6+8х=-х+33

8х+х=33-6

9х=27

х=27/9

х=3

2) -12х-18+9х=-9

-12х+9х=-9+18

-3х=9

х=9/(-3)

х=-3
