Question

Tentukan nilai x dari 18-(x-4) = 9+(x+3)

Answer 1

18 - (x - 4) = 9 + (x + 3)
18 - x + 4 = 9 + x + 3
22 - x = 12 + x
22 - 12 = x + x
10 = 2x
x = 10 : 2
x = 5

Answer 2

= 18 - (x-4) = 9 + (x+3)
= 18 -x + 4 = 9 + x + 3
= -x - x        = 9 + 3 - 18 - 4
= - 2x          = -10
=    x            = -10/-2
=    x            = 5
