Question

Determine o X
aa) 5x-3+X=2x+9
bb)17x-7x=X+18
cc)X+x-4=17-2x+1
dd)X+2x+3-5x=4x-9
ee)5x+6x-16=3x+2x-4
ff)5x+4=3x-2x+4
Me ajudemmmmmmmm

Answer 1

aa)
5x-3+x=2x+9
5x +x -2x = 9 + 3
6× - 2x = 12
4x = 12
x = 12/ 4
x = 3
Resposta x = 3

bb)
17x - 7x = x + 18
17x - 7x - x = 18 + 7
17x - 6x = 25
9x = 25
x = 25 / 9
Resposta x = 25/9

cc)
x+x-4=17-2x+1
x+x+2x= 17 +1+4
4x = 22
x = 22/4
Resposta x = 22/4
