Question

6.(x-3)=4.(x+4)
3.(3-x)+9=2.(x-4)+6
6.(x+5)=54
4.(x-8)=6-30

Answer 1

en la primera
$6x - 18 = 4x + 16 \\ 6x - 4x = 16 + 18 \\ 2x = 34 \\ x = \frac{34}{2} \\ x = 17$

en la segunda
$9 - 3x + 9 = 2x - 8 + 6 \\ 18 - 3x = 2x - 2 \\ 18 + 2 = 2x + 3x \\ 20 = 5x \\ \frac{20}{5} = x \\ 4 = x$

en la tercera

$6x + 30 = 54 \\ 6x = 54- 30 \\ 6x = 24 \\ x = \frac{24}{6} \\ x = 4$

en la cuarta

$x - 8 = - 24 \\ x = - 24 + 8 \\ x = - 16$
