Question

PLSV (Persamaan Linear Satu Variabel)

Answer 1

A.) 4x - 3 = 5
4x = 5 + 3
4x = 8
x = 8/4
x = 2

b.) 10x + 2 = 4x + 14
10x - 4x = 14 - 2
-6x = 12
x = 12/-6
x = -2

c.) 2(x - 3) = 3(x + 1)
2x - 6 = 3x + 3
2x - 3x = 3 + 6
-x = 9
x = -9

d.) -3(x - 1) = -4(x + 1)
-3x + 3 = -4x - 4
-3x + 4x = -4 - 3
x = -7

e.) 1/3 (x + 2) = 1/4 x + 1
-------------------- (dikali 12)
4(x + 2) = 3x + 12
4x + 8 = 3x + 12
4x - 3x = 12 - 8
x = 4

semoga membantu
