Answer 1

Respuesta:

$a)6x + 3 = 2x + 10 \\ 6x - 2x = 10 - 3 \\ 4x = 7 \\ x = \frac{7}{4}$

$b)40 + x = 3x + 15 \\ 40 - 15 = 3x - x \\ 25 = 2x \\ \frac{25}{2} = x$

$c)2q + 3 = 4q + 16 \\ 3 - 16 = 4q - 2q \\ - 13 = 2q \\ - \frac{13}{2} = q$

$d)3w - 17 = - 18 + w \\ 3w - w = - 18 + 17 \\ 2w = - 1 \\ w = - \frac{1}{2}$

$e)6x + 7 = - x + 15 \\ 6x + x = 15 - 7 \\ 7x = 8 \\ x = \frac{8}{7}$

$f)2b - 45 = - b + 60 \\ 2b + b = 60 + 45 \\ 3b = 105 \\ b = \frac{105}{3} \\ b = 35$

$g) - 4 + 3y = - 4y + 33 \\ 3y + 4y = 33 + 4 \\ 7y = 37 \\ y = \frac{37}{7}$

$h)6x + 4x = - x + 19 \\ 10x = - x + 19 \\ 10x + x = 19 \\ 11x = 19 \\ x = \frac{19}{11}$

$i) - 45 + 6x = - x +4 0 \\ 6x + x = 40 + 45 \\ 7x = 85 \\ x = \frac{85}{7}$
