Question

Tentukan himpunan penyelesaian dari persamaan berikut

F. 5( y - 1 ) = 4y
G. 4( 3 - 2y ) = 15 + 7y
H. 3( 2y - 3 ) = 5( y-2 )
I. 8 - 2( 3 + 4y ) = 7y1
J. 5x + 7 ( 3x+2 ) = 6( 4x + 1 )

Answer 1

Verified answer

F) 5(y - 1) = 4y
5y - 5 = 4y
5y - 4y = 5
y = 5

g) 4(3 - 2y) = 15 + 7y
12 - 8y = 15 + 7y
- 8y - 7y = 15 - 12
- 15y = 3
y = 3/-15
y = - ¹/5

h) 3(2y - 3) = 5(y - 2)
6y - 9 = 5y - 10
6y - 5y = - 10 + 9
y = - 1

i) soal kurang jelas tandanya (7y1)

j) 5x + 7(3x + 2) = 6 (4x + 1)
5x + 21x + 14 = 24x + 6
26x + 14 = 24x + 6
26x - 24x = 6 - 14
2x = - 8
x = - 4
