1. 3x-4=6-4x
2. 5(x+2)=20
3. 4(2x+3)=5x-3
4. 3x-6(2X-4)=8-5x
tolong di bantu
Jawaban:
[tex]3x - 4 = 6 - 4x \\ 3x - 4 + 4 = 6 - 4x + 4 \\ 3x = 10 - 4x \\ 3x + 4x = 10 - 4x + 4x \\ 7x = 10 \\ x = \frac{10}{7} [/tex]
[tex]5(x + 2) = 20 \\ 5x + 10 = 20 \\ 5x = 20 - 10 \\ 5x = 10 \\ x = \frac{10}{5} \\ x = 2[/tex]
[tex]4(2x + 3) = 5x - 3 \\ 8x + 12 = 5x - 3 \\ 8x + 12 - 12 = 5x - 3 - 12 \\ 8x = 5x - 15 \\ 8x - 5x = 5x - 5x - 15 \\ 3x = - 15 \\ x = \frac{ - 15}{3} \\ x = - 5[/tex]
[tex]3x - 6(2x - 4) = 8 - 5x \\ 3x - 12x + 24 = 8 - 5x \\ - 9x + 24 = 8 - 5x \\ - 9x + 24 - 24 = 8 - 5x - 24 \\ - 9x = - 16 - 5x \\ - 9x + 5x = - 16 - 5x + 5x \\ - 4x = - 16 \\ x = \frac{ - 16}{ - 4} \\ x = 4[/tex]
Jawaban:
jawaban dibawah
Penjelasan dengan langkah-langkah:
1. 3x-4=6-4x
3x+4x=6+4
7x=10
x=10/7
2. 5(x+2)=20
x+2=4
x=2
3. 4(2x+3)=5x-3
8x+12=5x-3
8x-5x=-3-12
3x=-15
x=-5
4. 3x-6(2X-4)=8-5x
3x-12x+24=8-5x
-9x+5x=8-24
-4x=-16
x=4
semoga membantu
