Question

16x-1=12x+3
3x-2=4x+9
5x-3+x=2x+9
17x-7x=x +18
X+x- 4=17-2x+1
X+2x+3-5x=4x-9
5x+6x-16=3x+2x-4
5x+4=3x-2x+4

Answer 1

16x - 1 = 12x + 3

x = 1

3x - 2 = 4x + 9

x = -11

5x - 3 + x = 2x + 9

x = 3

17x - 7x = x + 18

x = 2

X + x - 4 = 17 - 2x + 1

x = 5,5

X + 2x + 3 - 5x = 4x - 9

x = 2

5x + 6x - 16 = 3x + 2x - 4

x = 2

5x + 4 = 3x - 2x + 4

x = 0

Espero ajudar.
