Tentukanlah penyelasaian dari persamaan berikut: A. 8x-7 = 3+13x B. 10-3x =2(x+3) C. 3x-(2x-2) = 18 D. x+12 = 4x-3

a. 8x-13x=3+7
-5x=10
x=-2

b. 10-3x=2x+6
-3x-2x+6-10
-5x=-4
x=[tex] \frac{4}{5} [/tex]

c. 3x-2x+2=18
x+2=18
x=18-2=16

d. x+12 = 4x-3
x-4x=-3-12
-3x=-15
x=5

A. 8x - 7 = 3 + 13x
8x - 13x = 3 + 7
-5x = 10
x = 10/-5
x = -2

B. 10 - 3x = 2 ( x +3 )
10 - 3x = 2x + 6
-3x - 2x = 6 - 10
-5x = -4
x = -4/-5
x = 0,8

C. 3x - ( 2x - 2 ) = 18
3x - 2x + 2 = 18
3x - 2x = 18 - 2
x = 16

D. x + 12 = 4x - 3
x - 4x = -3 - 12
-3x = -15
x = -15/-3
x = 5
