Question

Pessoal Resolve aqui pra mim:

b) 5a + 6 = -29

c)2x + 11 = 3

d) 3x - 27 = -3

Answer 1

b) 5a + 6 = -29

5a = -29 - 6
5a = -35
a = -35/5
a = 7

==============================
c) 2x + 11 = 3

2x = 3 - 11
2x = -8
x = -8/2
x = -4

============================
d) 3x - 27 = -3

3x = -3 + 27
3x = 24
x = 24/3
x = 8

Answer 2

Olá boa tarde!

Veja a resolução abaixo:

b)

$5a + 6 = -29$

$5a=-29-6$

$5a=-35$

$A=\dfrac {-35}{5}$

$\boxed {\boxed {A=-7}}$

c)

$2x + 11 = 3$

$2x=3-11$

$2x=-8$

$X=\dfrac {-8}{2}$

$\boxed {\boxed {-4}}$

d)

$3x - 27 = -3$

$3x=-3+27$

$3x=-24$

$X=\dfrac {-24}{3}$

$\boxed {\boxed {-8}}$
