Question

Resolva as equações

a)
$2x = 10$
b)
$2x + 3x = 25$
c)
$1 {}^{6} + 3 {}^{2} =$
$7x - 3x = 24$
$3(x + 2) = 8$
​

Answer 1

a= X=5

b= x=5

o resto n sei

Answer 2

Resposta:

a) 2x=10 -> x=10/2 -> x= 5

b) 2x + 3x=25 -> 5x=25 -> x=25/5 -> x= 5

c) 1⁶+3² -> 1 + 9 = 10

d) 7x - 3x=24 -> 4x=24 -> x= 24/4 -> x = 6

e) 3(x+2)=8 -> 3x + 6=8 -> 3x=8-6 -> 3x=2 -> x= 2/3
