Nt : tyy​

Jawaban:

5x + 10 = 2x + 52

5x + 10 - 10 = 2x + 52 - 10

5x = 2x + 42

5x - 2x = 2x + 42 - 2x

3x = 42

x = 42/3

x = 14

Jawab:
x = 14

Penjelasan:
5x + 10 = 2x + 52
5x - 2x = 52 - 10
3x = 42
x = 42/3
x = 14

Bukti:
5x + 10     = 2x + 52
5(14) + 10 = 2(14) + 52
70 + 10 = 28 + 52
80 = 80
