Question

(son ecuaciones) ayuda no se cono resolver esto doy corona si me ayudan.


3 x mas 9 = 30
1 x mas 3 =8
4 x mas 2=26

Answer 1

Respuesta:

$3x + 9 = 30 \\ 3x = 30 - 9 \\ 3x = 21 \\ x = 21 \div 3 \\ x = 7$

$1x + 3 = 8 \\ 1x = 8 - 3 \\ 1x = 5 \\ x = 5 \div 1 \\ x = 5$

$4x + 2 = 26 \\ 4x = 26 - 2 \\ 4x = 24 \\ x = 24 \div 4 \\ x = 6$
