Answer 1

-Hola buenas tardees

a)

$5x + 9 = 49 \\ 5x = 49 - 9 \\ 5x = 40 \\ x = 40 \div 5 \\ x = 8$

b)

$2x + 9 = 13 \\ 2x = 13 - 9 \\ 2x = 4 \\ x = 4 \div 2 \\ x = 2$

c)

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

d)

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

e)

$5x + 4 = 49 \\ 5x = 49 - 4 \\ 5x = 45 \\ x = 45 \div 5 \\ x = 9$

Espero haberte ayudado ♡
