equações

a) 7.(x+8)=9x-1


B) 4x+5-10=7x+3​

Answer 1

Resposta:

a)

$7 \times (x + 8) = 9x - 1$

$7x + 56 = 9x - 1$

$2x = 57$

$x = 28.5$

b)

$4x + 5 - 10 = 7x + 3$

$3x = - 8$

$x = - 2.666666$

Answer 2

Resposta:

a)7x+56=9x-1

-56+1=9x-7x

-57=2x

X=57÷2

X=-28,5

b)4x+5-10=7x+3

5-10-3=7x-4x

-18=3x

X=-18÷3

X=-6
