1)

$x = 1.5 \times 2.4 \\ x = 3.6$

2)

$x + 0.15 = \frac{1}{2} \times 2.3 \\ x + 0.15 = 1.15 \\ x = 1.15 - 0.15 \\ x = 1$

$3)x + 0.1 = 4.7 \times 3 \\ x + 0.1 = 14.1 \\ x = 14.1 - 0.1 \\ x = 14$

$4) \frac{23 - x}{4} = \frac{11}{2} \\ 23 - x = \frac{11}{2} \times 4 \\ 23 - x = 22 \\ x = 23 - 22 \\ x = 1$

Answer 2

1) х = 1,5*2.4 =3.6
2) х = 1/2 * 2.3 - 0.15 = 1
3) х = 4.7*3-0.1 = 14
4) х = 23 - 22 = 1
