Question

Mohon dijawab yah..
1.3x + 11 = -28
2.-4 - 15 = 1 - 8x

Answer 1

1. 3x + 11 = -28
3x = -28 - 11
3x = -39
x = -13

2. -4 -15 = 1 - 8x
-19 = 1- 8x
-19 - 1 = -8x
-20 = -8x
x = 20/8
x = 5/2 = 2,5
semoga dapat di pahami

Answer 2

1.3x + 11 = -28
3x=-28-11
3x=-39
x=-13

2.-4 - 15 = 1 - 8x
-19 - 1 =-8x
-20=-8x
2,5 = x

klu soalnya 4x

-4x - 15 = 1 - 8x
-15 - 1 =-8x + 4x
-16 = -4x
4 = x
