Hasil dari 3(×-10)=4(2×-5) adalah? tolong pakai caranya ya ka

Jawaban:

3(x – 10) = 4(2x – 5)

3x – 30 = 8x – 20

3x – 8x = -20 + 30

-5x = 10

x = -10/5

x = -2

Jawaban:

3(x-10) = 4(2x-5)

3x-30 = 8x-20

3x-8x = -20+30

-5x = 10

x = 10/-5

x = (-2)

jadi,x adalah (-2)

3(x-10) => 3(-2-10) = 3.(-12)

= (-36)

4(2x-5) => 4(2.(-2)-5)= 4(-4-5)

= 4.(-9) = (-36)
