Answer 1

Jawaban:

1. 4x-7=3

4×=3+7

4×=10

×=10÷4

×=2,5

2. 7×=12+×

×=3

Answer 2

Jawaban:

1) x= 2,5

2) x= 2

3) x= -1

4) x= 3

Penjelasan dengan langkah-langkah:

1)

4x - 7 = 3

ㅤㅤ4x = 3 + 7

ㅤㅤ4x = 10

ㅤ ㅤ x = 10/4

ㅤㅤ x = 2,5

2)

ㅤ 7x = 12 + x

7x - x = 12

ㅤ 6x = 12

ㅤ x = 12/6

ㅤ x = 2

3)

12x + 10 = -4 - 2x

12x + 2x = -4 - 10

ㅤ ㅤ14x = -14

ㅤ ㅤㅤ x = -14/14

ㅤ ㅤㅤx = -1

4)

4x - 14 = 10 - 4x

4x + 4x = 10 + 14

ㅤㅤ8x = 24

ㅤㅤㅤx = 24/8

ㅤㅤㅤx = 3
