bantu kak, besok di kumpulin
1) x + 11 = 17
x = 17 - 11
x = 6
2) y - 13 = 16
y = 16 + 13
y = 29
3) 6x + 7 = 25
6x = 25 - 7
6x = 18
x = 18/6
x = 3
4) 8x - 8 = 32
8x = 32 + 8
8x = 40
x = 40/8
x = 5
5) y² + 6 = 42
y² = 42 - 6
y² = 36
y = √36
y = 6 atau -6
6) m² - 13 = 51
m² = 51 + 13
m² = 64
m = √64
m = 8 atau -8
7) 6x + 10 = 4x + 40
6x - 4x = 40 - 10
2x = 30
x = 30/2
x = 15
8) 7 - 3x = 7x - 37
7 + 37 = 7x + 3x
44 = 10x
x = 44/10
x = 4,4
