Question

Ecuaciones necesito ayuda ¡¡¡
3 . (x - 1) = 3
3 . ( x -2) + 2 . (x - 1 ) = 27
aplicar la propiedad distributiva
8 . (x + 2)
9 . ( 8x - 7)
[ 61/ √100+ √ 49/25 + ( 2^2 + √25) - 2^1] √25/2^2=

Answer 1

3x - 3 = 3
3x = 3 + 3
x = 6/3
x = 2

3x - 6 + 2x - 2 = 27
5x - 8 = 27
5x = 27 + 8
x = 35/5
x = 7

8x + 16

72x - 63

(61/10 + 7/5 + (4 + 5) - 2)*5/4
((61 + 14 + 9*10 - 2*10)/10)*5/4
(185/10)*5/4
185/8 = 23,125
