Question

tentukan penyelesaian dari persamaan linear satu variabel​

Answer 1

Penjelasan dengan langkah-langkah:

a.

X + 8 = 15

X = 15 - 8

X = 7

b.

X + 5 = -12

X = -12 - 5

X = -17

c.

X + 16 = 1

X = 1 - 16

X = -15

d.

X - 9 = 10

X = 10 + 9

X = 19

e.

X - 14 = 18

X = 18 + 14

X = 32

z.

2P + 9 = 36

2P = 36 - 9

2P = 27

2P = 27

2 × P = 27

P = 27 ÷ 2

P = 13,5

6P + 7 = 43

6P = 43 - 7

6P = 36

6P = 36

6 × P = 36

P = 36 ÷ 6

P = 6
