Question

resolva as equações do 1° grau
A)10-5x+1=2x-7

B)3x-7=4x+11

C)5(x-3)+2=-x+23​

Answer 1

a) 10-5x+1=2x-7

   $-5x-2x=-10-1-7$

   $-7x=-18$

   $x=\frac{-18}{-7}$

   $x=\frac{18}{7}$

b) 2x-7=4x+11

    $3x-4x=11+7$

   

c) 5(x-3)+2=-x+23

    $5x-15+2=-x+23$

    $5x+x=23+15-2$

    $6x=36$

    $x=\frac{36}{6}$

    $x=6$

Espero ter ajudado. Bons Estudos!
