Question

1/4 (x - 8) = 8 + 2/3 x adalah b
Nilai dari b + 7 = …

Answer 1

1/4(x-8)= 8+2/3×
------------------ ×12 (samainpenyebut)
3(x-8)= 96+8×
3x-24=96+8x
3x-8x=96+24
-5×=120
x=120/-5
×= -24

nilai b+7
-24+7
-17

Answer 2

1/4(x -8) = 8 +2/3x
1/4x -2 = 8 +2/3x
1/4x -2/3x = 8 +2
3/12x -8/12x = 10
-5/12x = 10
x = 10 : -5/12
x = 10 . 12/-5
x = -24
x = b

Maka,
b +7
= -24 +7
= -17

Itu jawabannya.
