b.2-4x=3
c.x-12=2x+36
d.-5x-4x+10=1
e.2+(x/4)=5
jika x adalah bilangan asli tentukan himpunan penyelesaian dari persamaan linearnya
A.6x+5=26-x
Jawaban Terkonfirmasi
A. 6x +5 = 26 -x
6x +x = 26 -5
7x = 21
x = 3
HP = {3}
b. 2 -4x = 3
-4x = 3 -2
-4x = 1
x = -1/4
HP = { }
c. x -12 = 2x +36
x -2x = 36 +12
-x = 48
x = 48
HP = { }
d. -5x -4x +10 = 1
-9x = 1 -10
-9x = -9
x = 1
HP {1}
e. 2 +(x/4) = 5
x/4 = 5 -2
x/4 = 3
12 = x
x = 12
HP = {12}
Itu jawabannya.
A. 6x + 5 = 26 – x
7x = 21
x = 3
b. 2 – 4x = 3
– 4x = 1
x = -1/4
c. x – 12 = 2x + 36
– x = 48
x = -48
d. – 5x – 4x + 10 = 1
– 9x = -9
x = 1
e. 2 + (x/4) = 5
x/4 = 3
x = 12
