Question

1.)5x+13=-12 2.)7x-8=-20 3.)2x+7=14-3x 4.)6-x=5x+30 tolong dijawab ya:)

Answer 1

Jawab =
1) 5x+13=-12
5x=-12-13
5x=-25
x = -25/5
x = -5
2) 7x-8 = -20
7x = -20+8
7x = -12
x = -12/7 (yang ini gak salah soal kan?)
3) 2x+7 = 14-3x
2x+3x = 14-7
5x = 7
× = 7/5
4) 6-x = 5x+30
-x-5x = 30-6
-6x = 24
x = 24/-6
x = -4

Answer 2

1)

5x+13 = - 12
5x = - 12-13
5x = -25
x = - 5


2)

7x-8 = - 20
7x = -20+8
7x = - 12
x = - 12/7


3)

2x+7=14-3x
2x+3x = 14-7
5x = 7
x = 7/5

4)

6-x=5x+30
-x-5x = 30-6
-6x = 24
x = -4
