Question

resolva as equações do 1 grau

Answer 1

5x-2x= - 4 - 2
3x = - 6
x= - 6/2
x= - 3

5(3x - 2) =2( x +3)
15x - 10 = 2x + 6)
15x - 2x = 6+10
13x = 16
x = 16/13
Um abraço.

Answer 2

Resposta:

a) - 2

$b)\frac{16}{3}$

Explicação passo-a-passo:

$a)5x+2=2x-4\\5x-2x=-4-2\\3x=-6\\x=-\frac{6}{3} \\\boxed{x=-2}$

$b)5(3x-2)=2(6x+3)\\15x-10=12x+6\\15x-12x=6+10\\3x=16\\\boxed{x=\frac{16}{3} }$
