Question

1: determine x:
a: 6x=2x +16

b: 9x +9+3x=15

c: 3x-2=4x+9​

Answer 1

$a) \\ 6x = 2x + 16 \\ 6x - 2x = 16 \\ 4x = 16 \\ x = \frac{16}{4} \\\boxed{\boxed{\boxed{x = 4}}}$

$b) \\ 9x + 9 + 3x = 15 \\ 9x + 3x = 15 - 9 \\ 12x = 6 \\ x = \frac{6}{12} \\ \boxed{\boxed{\boxed{x = \frac{1}{2} }}}$

$c) \\ 3x - 2 = 4x + 9 \\ 3x - 4x = 9 + 2 \\ - x = 11 \\ \boxed{\boxed{\boxed{x = - 11}}}$
