Question

Selesaikan persamaan berikut
a. x - 5 = -2
b. 4y + 8 = 2y
c. 2x + 6 =4x - 12
d. 4 (1-p) = 3 (p+5)

pakai cara

Answer 1

A) x - 5 = 2
x = 7

b) 4y + 8 = 2y
4y - 2y = - 8
2y = - 8
y = - 4

c) 2x + 6 = 4x - 12
4x - 2x = 6 + 12
2x = 18
x = 9

d) 4(1 - p) = 3(p + 5)
4 - 4p = 3p + 15
3p + 4p = 4 - 15
7p = - 11
p = - 11/7
