Question

Tolong kasih tau caranya jawab soal2 PLSV dibawah ini donk!!!dikumpulin besok...cepet jawab
1. 3(1-q)+4(q-5)=-5
2. 4x+3(x-2)-(5-4x)=0
3. 3(2x-3)-2(x+1)=x-3
4. 8y-5(2y-3)=4(y-3)+18
5. 5(2y+4)-(10y-16)=6-4y

Answer 1

1. 3(1-q)+4(q-5)=-5
==> (3 - 3q) + (4q - 20) = -5
q - 17 = -5
q = 12

2. 4x+3(x-2)-(5-4x)=0
==> 4x + (3x - 6) - (5 - 4x) = 0
(4x + 3x + 4x) + (-6 - 5) = 0
11x - 11 = 0
11x = 11
x = 1

3. 3(2x-3)-2(x+1)=x-3
==> (6x - 9) + (-2x - 2) = x - 3
(6x - 2x) + (-9 - 2) = x - 3
4x - 11 = x -3
4x - x = 11 - 3
3x = 8
x = 8/3

4. 8y-5(2y-3)=4(y-3)+18
==> 8y + (-10y + 15) = (4y - 12) + 18
8y - 10y - 4y = -15 - 12 + 18
-6y = -9
y = 9/6 = 3/2

5. 5(2y+4)-(10y-16)=6-4y
==> (10y + 20) + (-10y + 16) = 6 - 4y
10y -10y + 4y = 6 - 20 -16
4y = -30
y = -30/4 = -15/2

Answer 2

1. 3-3q+4q-20+5 = 0 => q = -12
2. 4x+3x-6-5+4x=0 =>x = 1
3. 6x-9-2x-2+x+3=0 => x = 7 /5
4. 8y-10y+15+4y+12-18 = 0 => y = 9/14
5. 10y+20-10y+16-6+4y = 0 =>y = 30/4

coba diitung sekali lagi ya, nda yakin kalau jumlah2annya tepat
