Question

me ajuda pessoal
A)4.(x+3)-x=24+x
B)9x+75=34
x
C) 18x - 43= 65

Answer 1

a) 4.(x+3) - x = 24 + x
    4x + 12 - x = 24 + x
    3x + 12 = 24 + x
    3x - x = 24 - 12
    2x = 12
    x = 12/2
    x = 6

b) 9x/x + 75 = 34
    9x/x = 34 - 75
    9x/x = - 41
    9x = - 41x
    9x + 41x = 0
    50x = 0
    x = 0
    

c) 18x - 43 = 65
    18x = 65 + 43
    18x = 108
    x = 108/18
    x = 6

Answer 2

'a-4x+16-x=24+x
4x+x-x=24-16
4x=12
x=12÷4
x=3
b-9x=34-75
9x=41
x=41÷9
x=4
