Odpowiedź:
1.
3 = 6 - x / + x
x + 3 = 6 / - 3
x = 3
2.
6 x + 24 = 5 x + 1 + x / -x
5x + 24 = 5x + 1 / -24
5x = 5x - 23 / - 5x
0 = -23
3.
3x + 9 = 2x + 8 + x + 1
3x + 9 = 3x + 9 / -9
3x = 3x / - 3x
0 = 0
4.
1/2y + 3 = 7 / -3
[tex]\frac{1}{2}y[/tex] = 4 / * 2
y = 8
5.
2/3x - 1/6 = 3 / + 1/6
2/3x = 3[tex]\frac{1}{6}[/tex]
2/3x = 19/6 / * 3
3 * 2/3x = 19/6 * 3
x = 19 /4
ale nie jestem pewny ostatniego
