Question

6x= 2x+16
4x-10= 2x+2
2x+1 = 4x-7
3x-2= 4x-9
5x+4 = 3x-2x+4
x+x-4 = 17 - 2x + 1
3,4x-2,6 = x- 0,92 0,1x
3x + 0,9 = 14+ 2x

Answer 1

Resposta:

$6x = 2x + 16 \\ \\ x = 4$

$4x - 10 = 2x + 2 \\ \\ x = 6$

$2x + 1 = 4x - 7 \\ \\ x = 4$

$3x - 2 = 4x - 9 \\ \\ x = 3$

$5x + 4 = 3x - 2x + 4 \\ \\ x = 0$

$x + x - 4 = 17 - 2x + 1 \\ \\ x = \frac{11}{2}$

$3.4x - 2.6 = x - 0.92 \\ \\ x = 0.7$

$3x + 0.9 = 14 + 2x \\ \\ x = 13.1$
