Question

Jika x = bilangan asli, tentukan himpunan persamaan linear berikut :
1. 6x + 5 = 26 - x
2. 2 - 4x = 3
3. x - 12 = 2x + 36
4. -5x - 4x + 10 = 1
5. 2 + x per 4 = 5

please bantuu!!

Answer 1

1.
6x + 5 = 26 - x
6x + x = 26 - 5
7x = 21
x = 21/ 7
x= 3

2.
2 - 4x = 3
-4x = 3 - 2
-4x = 1
???

3.
x - 12 = 2x + 36
x - 2x = 36 + 12
-x = 48
x = -48

4.
-5x - 4x + 10 = 1
-5x - 4x = 1 - 10
-9x = -9
x = -9/-9
x = 1

Answer 2

1. 6x+5=26-x
=6x+x=26-5
=7x=21
= x=3
2. 2-4x=3
=-4x=3-2
-4x=1
x=1/-4
3. x-12=2x+36
x-2x=36+12
-x=48
x=-48
4. -5x-4x+10=1
-5x-4x=1-10
-9x=-9
x=1
5. 2+x/4=5
x/4=5-2
x/4=3
x=3×4
x=12
