Question

Tentukan nilai variabel berikut!
1. 4+m=11
2.8=a+3
3.x-9=26
4.14=p-4
5 2x-4=8
6.x-8=-5
7.-4+3y=20
8.10=p-6
9.5(y-2)=y-2
10.2a+1=5

Answer 1

1) 4 + m = 11
= m = 11 - 4
= m = 7

2) 8 = a + 3
= 8 - 3 = a
= 5 = a

3) x - 9 =26
= x = 26 + 9
= x = 35

4) 14 = p - 4
= 14 + 4 = p
= 18 = p

5) 2x - 4 = 8
= 2x = 8 + 4
= 2x = 12
= x = 12/2
= x = 6

6) x - 8 = - 5
= x = - 5 + 8
= x = 3

7) -4 + 3y = 20
= 3y = 20 + 4
= 3 y = 24
= y = 24/3
= y = 8

8) 10 = p - 6
= 10 + 6 = p
= 16 = p

9) 5 (y - 2) = y - 2
= 5y - 10 = y - 2
= 5y - y = -2 + 10
= 4y = 8
= y = 8/4
= y = 2

10) 2a + 1 = 5
= 2a = 5 - 1
= 2a = 4
= a = 4/2
= a = 2

Maaf kalau ada yang salah:)
Semoga membantu:D
