kuizz[+50] 1.) x + 7 = 4x + 10 maka x = __ 2.) l 2x - 10 l = 2 HP = {...,...} ​

Jawaban:

1.) x + 7 = 4x + 10 maka x = -1

2.) l 2x - 10 l = 2 HP = { 4, 6 }

Penjelasan dengan langkah-langkah:

1.

x + 7 = 4x + 10

x - 4x = 10 - 7

-3x = 3

x = 3 ÷ (-3)

x = - 1

2.

l 2x - 10 l = 2 HP

2x - 10 = 2

2x -10 = - 2

2x = 2 + 10

2x = -2 + 10

2x = 12

2x = 8

x= 12 ÷ 2

x= 8 ÷ 2

x= 4

x= 6
