h)4(x+3)=1

l)x+3=11

m)x-5=13

n)2x=10

o)6x+60=2x

p)x+7x=72​

Answer 1

Explicação passo-a-passo:

h)

$4x + 12 = 1 \\ 4x = 1 - 12 \\ 4x = - 11 \\ x = \frac{ 4}{ - 11} \\ x = - 0.36$

l)

$x + 3 = 11 \\ x = 11 - 3 \\ x = 8$

m)

$x - 5 = 13 \\ x = 13 + 5 \\ x = 18$

n)

$2x = 10 \\ x = \frac{10}{2} \\ x= 5$

o)

$6x + 60 = 2x \\ 6x - 2x = - 60 \\ 4x = - 60 \\ x = \frac{ - 60}{4} \\ x = - 15$

p)

$x + 7x = 72 \\ 8x = 72 \\ x = \frac{72}{8} \\ x = 9$
