Answer 1

Penjelasan dengan langkah-langkah:

3x + 2 = 8

3x = 6

x = 2

13 = 5x + 13

5x = 0

x = 0

4x - 1 = -13

4x = -12

x = -3

-5x - 4 = 2 - 3x

-5x + 3x = 2 + 4

-2x = 6

x = -3

----------(b a t a s)-------------

tentukan nilai a jika x = 2

x + a = 3

2 + a = 3

a = 1

2(x - a) = 5

2(2 - a) = 5

2 - a = 5/2

a = 2 - 5/2

a = 4/2 - 5/2

a = -1/2

ax + 5 = 7

ax = 2

2a = 2

a = 1
