Question

Necesito ayuda resuelve y verifica a)×+1=3 b)3×-3=3 c)3×-1=×+15 d)3×+22=×+8

Answer 1

A)

$x + 1 = 3 \\ x = 3 - 1 \\ x = 2$
B)
$3x - 3 = 3 \\ 3x = 3 + 3 \\ 3x = 6 \\ x = \frac{6}{3} \\ x = 2$
C)
$3x - 1 = x + 15 \\ 3x - x = 15 + 1 \\ 2x = 16 \\ x = \frac{16}{2} \\ x = 8$
D)
$3x + 22 = x + 8 \\ 3x - x = 8 - 22 \\ 2x = - 24 \\ x = \frac{ - 24}{2} \\ x = - 12$
