Question

Jawaban nya apa ya beserta cara nya biar tah

Answer 1

A. 3(6x+2) = 10x - 2(x+3)
18x +6 = 10x -2x-6
10x = -12 x= -12/10
b. 9- 2(4x-3) = 2x+5
9- 8x+6 = 2x + 5
10 = 10x x=1
c. 2x/5 = 3(x-4)/4
4.(2x) = 5.(3x-12)
8x = 15x -60
60 = 7x x = 60/7
d. 3(3x-1)/4 = 2(2x+3)/6
6.(9x-3) = 4.(4x+6)
54x -18 = 16x +24
38x =42 x =42/38=21/19

Answer 2

A. 3(6x+2) = 10x -2(x+3)
18x + 6 = 10x - 2x - 6
10x = -12
x = -1.2

b. 9-2(4x-3) = 2x+5
9 - 8x + 6 = 2x +5
-10x = -10
x = 1

c. 2/5x = 3/4(x-3)
2/5x = 3/4x - 9/4
2/5x - 3/4x = -9/4
-7/20x = -9/4
x = -9/4 x -20/7
x = 45 /7

d. 3/4(3x-1) = 2/6(2x +3)
------------------------------------- x 12
9(3x-1) = 4(2x+3)
27x - 9 = 8x +12
19x = 21
x = 21/19
