3×-7 =8
2×+1 =3​

Answer 1

Respuesta:

Ecuaciones:

$2x + 1 = 7 \\ 2x = 1 - 7 \\ 2x = 6$

$\large\boxed{\bold{Rpta: 2x=6}}$

$x + 1 = 2 \\ x = 2 - 1 \\ x = 1$

$\large\boxed{\bold{Rpta: x=1}}$

$3x - 5 = 1 \\ 3x = 5 + 1 \\ 3x = 6$

$\large\boxed{\bold{Rpta: 3x=6}}$

$2x - 3 = 1 \\ 2x = 3 + 1 \\ 2x = 4$

$\large\boxed{\bold{Rpta: 2x=4}}$

$x - 5 = 3 \\ x = 5 + 3 \\ x = 8$

$\large\boxed{\bold{Rpta: x=8}}$

$3x - 7 = 8 \\ 3x = 7 + 8 \\ 3x = 15$

$\large\boxed{\bold{Rpta: 3x=15}}$

$2x + 1 = 3 \\ 2x = 3 - 1 \\ 2x = 2$

$\large\boxed{\bold{Rpta: 2x=2}}$
