Question

resolva as equações

Answer 1

a - 4x -6=22
4x = 22 + 6
x = 28 / 4
x = 7
b - 9 - x = 2x
9 = 2x + x
9 = 3x
9/3 = x
x = 3
c - 8 + 4x = 6x - 4
8 + 4 = 6x - 4x
12 = 2x
12/2 = x
x = 6
d - 3x + 1 = 5 + x
3x - x = 5 -1
2x = 4
x = 4/2
x = 2
e - 4x -11 = 7 - 2x
4x + 2x = 7 + 11
6x = 18
x = 18/6
x = 3
f - 3x +1 = 5+x
3x -x = 5 -1
2x = 4
x = 4/2
x = 2
