soal di lampiran ya ☺☺☺☺
Halo jawaban ada di atas ok...
#Selamat belajar
a.
[tex]2x - 4 = 8 \\ 2x = 8 + 4 \\ 2x = 12 \\ x = 12 \div 2 \\ x = 6[/tex]
b.
[tex]
- 4 + 3s = 24 \\ 3s = 24 + 4 \\ 3s = 28 \\ s = \frac{28}{3} \\ s = 9.33[/tex]
c.
[tex]- 8 - {d}^{2} = 32 \\ - {d}^{2} = 32 + 8 \\ - {d}^{2} = 40 \\ - d = \sqrt{ 40} \\ - d = 2 \sqrt{10} \\ d = - 2 \sqrt{10}[/tex]
d.
[tex]5(u - 2) = u - 2 \\ 5u - 10 = u - 2 \\ 5u - u - 10 = - 2 \\ 4u = - 2 + 10 \\ 4u = 8 \\ u = 8 \div 4 \\ u = 2[/tex]
e.
[tex]2x - 1 = 5 \\ 2x = 5 + 1 \\ x = 6 \div 2 \\ x = 3[/tex]
f.
[tex] - 3 = x \\ x = - 3[/tex]
g.
[tex]{x}^{2} + 7 = 9 \\ {x}^{2} = 9 - 7 \\ {x}^{2} = 2 \\ x = \sqrt{2 } \\ x = 1.41421[/tex]
h.
[tex] {5}^{2} - 7x = 9 \\ 25 - 7x = 9 \\ - 7x = 9 - 25 \\ - 7x = - 16 \\ 7x = 16 \\ x = \frac{ 16}{ 7} \\ x = 2 \frac{2}{7} \\ x = 2.285[/tex]
j.
[tex]10 = x + 6 \\ 10 - 6 = x \\ x = 4[/tex]
maaf kalau salah
