A.) 2(5 - 2q) = 3(5 - q)
b.) -2 q + 5 = -(q + 9)
c.) 18 - 7 q = 2(3 q - 4)
d.) 3(2 q - 3) - 2(1 - q) - (q + 3) = 0
Tentukan nilai q
tolong bantu jawab ya.. makasih

PsygaTheta A. 2 (5 - 2q) = 3 (5 - q)
10 - 4q = 15 - 3q
-q = 5
q = -5

B. - 2q + 5 = - (q + 9)
- 2q + 5 = - q - 9
-q = -14
q = 14

C. 18 - 7q = 2 (3q - 4)
18 - 7q = 6q - 8
-13q = -26
q = ²⁶/₁₃
q = 2

D. 3 (2q - 3) - 2 (1 - q) - (q + 3) = 0
6q - 9 - 2 + 2q - q - 3 = 0 [Pindahkan angka ke kanan, yang memiliki q tetap di kiri]
6q + 2q - q = 9 + 2 + 3
7q = 14
q = 2

Semoga Membantu ^ ^

zwa A. 2(5-2q) = 3(5-q)
   = 10-4q = 15-3q
   = 10-15 = -3q+4q
   = -5 = q
b. -2q+5 = -(q+9)
   = -2q+5=-q-9
   = -2q+q=-9-5
   = -1q   = -14
   = q = $\frac{-14}{-1}$
   = q = 14
c. 18-7q = 2(3q-4)
   =18-7q=6q-8
   =18+8=6q+7q
   = 26=13q
   = $\frac{26}{13}$ =q
   = 2 =q
d.3(2q-3)-2(1-q)-(q+3) = 0
= 6q-9-2+2q-q-3 =0
= 8q-14 = 0
= 8q = 14
= q = $\frac{14}{8}$
= q = 1.75 atau $\frac{7}{4}$
